| 2 Material accounting policiesa. Financial instruments
i.    Recognition and initial measurement Trade receivables and debt securities issued are initiallyrecognised when they are originated. All other financial assets
 and financial liabilities are initially recognised when the Company
 becomes a party to the contractual provisions of the instrument.
 A financial asset or financial liability is initially measured at fairvalue plus, for an item not at fair value through profit and loss
 (FVTPL), transaction costs that are directly attributable to its
 acquisition or issue.
 ii.    Classification and subsequent measurement Financial assets On initial recognition, a financial asset is classified as measured at —    amortised cost; —    Fair value through other comprehensive income (FVOCI) -equity investment; or
 —    Fair value through profit and loss (FVTPL) Financial assets are not reclassified subsequent to their initialrecognition, except if and in the period the Company changes its
 business model for managing financial assets.
 A financial asset is measured at amortised cost if it meets both ofthe following conditions and is not designated as at FVTPL:
 —    the asset is held within a business model whose objective isto hold assets to collect contractual cash flows; and
 —    the contractual terms of the financial asset give rise onspecified dates to cash flows that are solely payments of
 principal and interest on the principal amount outstanding.
 A debt investment is measured at FVOCI if it meets both of thefollowing conditions and is not designated as at FVTPL:
 —    the asset is held within a business model whose objectiveis achieved by both collecting contractual cash flows and
 selling financial assets; and
 —    the contractual terms of the financial asset give rise onspecified dates to cash flows that are solely payments of
 principal and interest on the principal amount outstanding.
 On initial recognition of an equity investment that is not heldfor trading, the Company may irrevocably elect to present
 subsequent changes in the investment's fair value in OCI
 (designated as FVOCI - equity investment). This election is made
 on an investment- by- investment basis.
 All financial assets not classified as measured at amortised cost orFVOCI as described above are measured at FVTPL. This includes
 all derivative financial assets. On initial recognition, the Company
 may irrevocably designate a financial asset that otherwise meets
 the requirements to be measured at amortised cost or at FVOCI
 as at FVTPL if doing so eliminates or significantly reduces an
 accounting mismatch that would otherwise arise.
 Equity investments All equity investments in scope of Ind AS 109 are measuredat fair value. Equity instruments which are held for trading
 and contingent consideration recognised by an acquirer in a
 business combination to which Ind AS 103 applies are classified
 as at FVTPL. For all other equity instruments, the Company may
 make an irrevocable election to present in other comprehensive
 income subsequent changes in the fair value. The Company
 makes such election on an instrument-by-instrument basis. The
 classification is made on initial recognition and is irrevocable.
 If the Company decides to classify an equity instrument as at
 FVOCI, then all fair value changes on the instrument, excluding
 dividends, are recognised in the OCI. There is no recycling of
 the amounts from OCI to the Statement of Profit and Loss, even
 on sale of investment. However, the Company may transfer the
 cumulative gain or loss to retained earnings. Equity instruments
 included within the FVTPL category are measured at fair value
 with all changes recognised in the Statement of Profit and Loss.
 Investments in subsidiaries Equity investments in subsidiaries are carried at cost lessaccumulated impairment losses, if any. Where an indication
 of impairment exists,the carrying amount of the investment
 is assessed and written down immediately to its recoverable
 amount. On disposal of investments in subsidiaries, the difference
 between net disposal proceeds and the carrying amounts are
 recognised in the Statement of Profit and Loss.
 Financial liabilities are classified as measured at amortised cost orFVTPL. A financial liability is classified as at FVTPL if it is classified
 as held- for- trading, or it is a derivative or it is designated as such
 on initial recognition. Financial liabilities at FVTPL are measured
 at fair value and net gains and losses, including any interest
 expense, are recognised in statement of profit and loss. Other
 financial liabilities are subsequently measured at amortised cost
 using the effective interest method. Interest expense and foreign
 exchange gains and losses are recognised in statement of profit
 and loss. Any gain or loss on derecognition is also recognised in
 statement of profit and loss.
 iii. DerecognitionFinancial assets
 The Company derecognises a financial asset when thecontractual rights to the cash flows from the financial asset
 expire, or it transfers the rights to receive the contractual cash
 flows in a transaction in which substantially all of the risks and
 rewards of ownership of the financial asset are transferred or in
 which the Company neither transfers nor retains substantially all
 of the risks and rewards of ownership and does not retain control
 of the financial asset.
 When the Company has transferred its rights to receivecash flows from an asset or has entered into a pass-through
 arrangement, it evaluates if and to what extent it has retained the
 risks and rewards of ownership. When it has neither transferred
 nor retained substantially all of the risks and rewards of the asset,
 nor transferred control of the asset, the Company continues to
 recognise the transferred asset to the extent of the Company's
 continuing involvement. In that case, the Company also
 recognises an associated liability. The transferred asset and the
 associated liability are measured on a basis that reflects the rights
 and obligations that the Company has retained.
 Financial liabilities The Company derecognises a financial liability when itscontractual obligations are discharged or cancelled, or expire.
 The Company also derecognises a financial liability when itsterms are modified and the cash flows under the modified terms
 are substantially different. In this case, a new financial liability
 based on the modified terms is recognised at fair value. The
 difference between the carrying amount of the financial liability
 extinguished and the new financial liability with modified terms
 is recognised in statement of profit and loss.
 iv.    Offsetting Financial assets and financial liabilities are offset and the netamount presented in the balance sheet when, and only when,
 the Company currently has a legally enforceable right to set off
 the amounts and it intends either to settle them on a net basis or
 to realise the asset and settle the liability simultaneously.
 v.    Derivative financial instruments and hedge accounting The Company holds derivative financial instruments to hedgeits foreign currency and interest rate risk exposures. Embedded
 derivatives are separated from the host contract and accounted
 for separately if the host contract is not a financial asset and
 certain criteria are met.
 Derivatives are initially measured at fair value. Subsequent toinitial recognition, derivatives are measured at fair value, and
 changes therein are generally recognised in statement of profit
 and loss.
 The Company designates certain derivatives as hedginginstruments to hedge the variability in cash flows associated
 with highly probable forecast transactions arising from changes
 in foreign exchange rates and interest rates.
 At inception of designated hedging relationships, the Companydocuments the risk management objective and strategy for
 undertaking the hedge. The Company also documents the
 economic relationship between the hedged item and the
 hedging instrument, including whether the changes in cash
 flows of the hedged item and hedging instrument are expected
 to offset each other.
 vi.    Cash flow hedges When a derivative is designated as a cash flow hedginginstrument, the effective portion of changes in the fair value of
 the derivative is recognised in OCI and accumulated in other
 equity under 'effective portion of cash flow hedges'. The effective
 portion of changes in the fair value of the derivative that is
 recognised in OCI is limited to the cumulative change in fair
 value of the hedged item, determined on a present value basis,
 from inception of the hedge. Any ineffective portion of changes
 in the fair value of the derivative is recognised immediately in
 statement of profit and loss.
 If a hedge no longer meets the criteria for hedge accountingor the hedging instrument is sold, expires, is terminated or is
 exercised, then hedge accounting is discontinued prospectively.
 When hedge accounting for cash flow hedges is discontinued,
 the amount that has been accumulated in other equity remains
 there until, for a hedge of a transaction resulting in recognition
 of a non-financial item, it is included in the non-financial item's
 cost on its initial recognition or, for other cash flow hedges, it is
 reclassified to profit or loss in the same period or periods as the
 hedged expected future cash flows affect profit or loss.
 If the hedged future cash flows are no longer expected to occur,then the amounts that have been accumulated in other equity
 are immediately reclassified to statement of profit and loss.
 vii.    Treasury shares The Company has created an Employee Welfare Trust (EWT) forproviding share-based payment to its employees. Own equity
 instruments that are reacquired (treasury shares) are recognised
 at cost and deducted from equity. When the treasury shares
 are issued to the employees by EWT, the amount received is
 recognised as an increase in equity and the resultant gain / (loss)
 is transferred to / from securities premium.
 viii.    Cash and cash equivalents Cash and cash equivalents in the balance sheet comprisecash at banks and on hand and short-term deposits with an
 original maturity of three months or less, which are subject
 to an insignificant risk of changes in value. For the purpose of
 the statement of cash flows, cash and cash equivalents consist
 of cash and short-term deposits, as defined above, net of
 outstanding bank overdrafts as they are considered an integral
 part of the Company's cash management.
 Cash dividend to equity holders The Company recognises a liability to make cash to equity holderswhen the distribution is authorised and the distribution is no
 longer at the discretion of the Company. As per the corporate
 laws in India, a distribution is authorised when it is approved by
 the shareholders. A corresponding amount is recognised directly
 in equity. Interim dividends are recorded as a liability on the date
 of declaration by the Company's Board of Directors.
 b. Property, plant and equipmenti. Recognition and measurement Items of property, plant and equipment are measured at cost lessaccumulated depreciation and accumulated impairment losses,
 if any. The cost of an item of property, plant and equipment
 comprises its purchase price including import duty and non
 refundable taxes or levies , any other costs directly attributable
 to bringing the item to working condition for its intended use,
 and estimated costs of dismantling and removing the item and
 restoring the site on which it is located.
 Expenditure incurred on startup and commissioning of theproject and/or substantial expansion, including the expenditure
 incurred on trial runs (net of trial run receipts, if any) up to
 the date of commencement of commercial production are
 capitalised.If significant parts of an item of property, plant and
 equipment have different useful lives, then they are accounted
 for as separate items (major components) of property, plant and
 equipment.
 Any gain or loss on disposal of an item of property, plant andequipment is recognised in statement of profit and loss.
 Subsequent expenditure is capitalised only if it is probable that the future economic benefits associated with the expenditure will flow to theCompany and cost can be measured reliably.
 Advances paid towards acquisition of property, plant and equipment outstanding at each Balance Sheet date, are shown under other non-currentassets and cost of assets not ready for intended use before the year end, are shown as capital work-in-progress.
 ii. Depreciation Depreciation is calculated on cost of items of property, plant and equipment less their estimated residual values over their estimated useful livesusing the straight-line method. Freehold land is not depreciated.
 The estimated useful lives of items of property, plant and equipment for the current and comparative periods are as follows: Depreciation method, useful lives and residual values arereviewed at each financial year-end and adjusted if appropriate.
 Based on technical evaluation and consequent advice, the
 management believes that its estimates of useful lives as given
 above best represent the period over which management
 expects to use these assets.
 Depreciation on additions (disposals) is provided on a pro-ratabasis i.e. from (upto) the date on which asset is ready for use
 (disposed of).
 iii. Reclassification to investment property When the use of a property changes from owner-occupied toinvestment property, the property is reclassified as investment
 property at its carrying amount on the date of reclassification.
 Intangible assetsInternally generated: Research and development Expenditure on research activities is recognised in statement of profitand loss as incurred.
 Development expenditure is capitalised as part of the cost of theresulting intangible asset only if the expenditure can be measured
 reliably, the product or process is technically and commercially feasible,
 future economic benefits are probable, and the Company intends to
 and has sufficient resources to complete development and to use or
 sell the asset. Otherwise, it is recognised in statement of profit and lossas incurred. Subsequent to initial recognition, the asset is measured at
 cost less accumulated amortisation and any accumulated impairment
 losses.
 Others Other intangible assets are initially measured at cost. Subsequently,such intangible assets are measured at cost less accumulated
 amortisation and any accumulated impairment losses.
 Subsequent expenditure Subsequent expenditure is capitalised only when it increases thefuture economic benefits embodied in the specific asset to which it
 relates, and the cost of the asset can be measured reliably. All other
 expenditure, including expenditure on brands, is recognised in
 statement of profit and loss as incurred.
 Amortisation Intangible assets are amortised on a straight line basis over theestimated useful life as follows:
 —    Computer software    3-5 years —    Marketing and Manufacturing rights    5-10 years —    Customer related intangibles    5 years —    Intellectual property rights    5-10 years Amortisation method, useful lives and residual values are reviewed atthe end of each financial year and adjusted if appropriate.
 d.    Investment propertyInvestment property is property held either to earn rental income orfor capital appreciation or for both, but not for sale in the ordinary
 course of business, use in the production or supply of goods or
 services or for administrative purposes. Upon initial recognition,
 an investment property is measured at cost. Subsequent to initial
 recognition, investment property is measured at cost less accumulated
 depreciation and accumulated impairment losses, if any.
 Based on technical evaluation and consequent advice, themanagement believes a period of 25 years as representing the best
 estimate of the period over which investment properties (which are
 quite similar) are expected to be used. Accordingly, the Company
 depreciates investment properties over a period of 25 years on a
 straight-line basis. The useful life estimate of 25 years is different from
 the indicative useful life of relevant type of buildings mentioned in Part
 C of Schedule II to the Act i.e. 30 years. Any gain or loss on disposal of
 an investment property is recognised in statement of profit and loss.
 e.    Business combinationIn accordance with Ind AS 103, Business combinations, the Companyaccounts for business combinations after acquisition date using the
 acquisition method when control is transferred to the Company. The
 cost of an acquisition is measured at the fair value of the assets given,
 equity instruments issued and liabilities incurred or assumed at the
 date of exchange. The cost of acquisition also includes the fair value of
 any contingent consideration and deferred consideration, if any. Any
 goodwill that arises is tested annually for impairment. Any gain on a
 bargain purchase is recognised in OCI and accumulated in equity as
 capital reserve if there exists clear evidence of the underlying reasons
 for classifying the business combination as resulting in a bargain
 purchase; otherwise the gain is recognised directly in equity as capital
 reserve. Transaction costs are expensed as incurred.
 Business combinations between entities under common control isaccounted for at carrying value.
 f.    InventoriesInventories are measured at the lower of cost and net realisable value.The cost of inventories is based on the first-in first-out formula, and
 includes expenditure incurred in acquiring the inventories, production
 or conversion costs and other costs incurred in bringing them to
 their present location and condition. In the case of manufactured
 inventories and work-in-progress, cost includes an appropriate share
 of fixed production overheads based on normal operating capacity.
 Provisions are made towards slow-moving and obsolete items basedon historical experience of utilisation on a product category basis,
 which consideration of product lines and market conditions.
 Net realisable value is the estimated selling price in the ordinarycourse of business, less the estimated costs of completion and selling
 expenses. The net realisable value of work-in-progress is determinedwith reference to the selling prices of related finished products.
 Raw materials, components and other supplies held for use in theproduction of finished products are not written down below cost
 except in cases where material prices have declined and it is estimated
 that the cost of the finished products will exceed their net realisable
 value.
 The comparison of cost and net realisable value is made on an item-by-item basis.
 g.    Foreign currency Transactions and translations:Foreign currency transactions are translated into the functionalcurrency using the exchange rates at the dates of the transactions.
 Foreign exchange gains and losses resulting from the settlement of
 such transactions and from the translation of monetary assets and
 liabilities denominated in foreign currencies at balance sheet date
 exchange rates are generally recognised in Statement of Profit and
 Loss.
 Non-monetary items that are measured at fair value in a foreigncurrency are translated using the exchange rates at the date when
 the fair value was determined. Translation differences on assets and
 liabilities carried at fair value are reported as part of the fair value gain
 or loss. For example translation differences on non-monetary assets
 such as equity investments classified as FVOCI are recognised in other
 comprehensive income (OCI).
 h.    Impairmenti.    Impairment of financial assets In accordance with Ind AS 109, the Company applies expectedcredit loss ("ECL") model for measurement and recognition of
 impairment loss on following:
 — financial assets measured at amortised cost; and Loss allowance for trade receivables with no significantfinancing component is measured at an amount equal to
 lifetime expected credit losses. For all other financial assets,
 ECL are measured at an amount equal to the 12-month ECL,
 unless there has been a significant increase in credit risk
 from initial recognition in which case those are measured
 at lifetime ECL.
 Loss allowance for financial assets measured at amortisedcost are deducted from gross carrying amount of the assets.
 The amount of ECL (or reversal) that is required to adjust
 the loss allowance at the reporting date is recognised as an
 impairment gain or loss in the Statement of Profit and Loss.
 ii.    Impairment of non-financial assets The Company assess at each reporting date whether there is anyindication that the carrying amount may not be recoverable. If
 any such indication exists, then the asset's recoverable amount
 is estimated and an impairment loss is recognised if the carrying
 amount of an asset or Cash Generating Unit (CGU) exceeds its
 estimated recoverable amount in the statement of profit andloss.
 The recoverable amount of a CGU (or an individual asset) ishigher of its value in use and its fair value less costs to sell. Value
 in use is based on the estimated future cash flow, discounted
 to their present value using a pre-tax discount rate that reflects
 current market assessment of the time value of money and the
 risks specific to CGU (or the asset).
 The Company's non-financial assets, are reviewed at eachreporting date to determine whether there is any indication
 of impairment. If any such indication exists, then the asset's
 recoverable amount is estimated. For impairment testing, assets
 that do not generate independent cash inflows are grouped
 together into cash-generating units (CGUs). Each CGU represents
 the smallest group of assets that generates cash inflows that are
 largely independent of the cash inflows of other assets or CGUs.
 Impairment loss recognised in respect of a CGU is allocated firstto reduce the carrying amount of any goodwill allocated to the
 CGU, and then to reduce the carrying amounts of the other
 assets of the CGU (or group of CGUs) on a pro rata basis.
 An impairment loss in respect of other assets for whichimpairment loss has been recognised in prior periods, the
 Company reviews at each reporting date whether there is any
 indication that the loss has decreased or no longer exists. An
 impairment loss is reversed if there has been a change in the
 estimates used to determine the recoverable amount. Such
 a reversal is made only to the extent that the asset's carrying
 amount does not exceed the carrying amount that would have
 been determined, net of depreciation or amortisation, if no
 impairment loss had been recognised.
 
 i. Employee benefitsi.    Short-term employee benefits: All employee benefits falling due within twelve months fromthe end of the period in which the employees render the related
 services are classified as short-term employee benefits, which
 include benefits like salaries, wages, short term compensated
 absences, performance incentives, etc. and are recognised as
 expenses in the period in which the employee renders the
 related service and measured accordingly."
 ii.    Post-employment benefits: Post-employment benefit plans are classified into definedbenefits plans and defined contribution plans as under:"
 Gratuity The Company provides for gratuity, a defined benefit plan ("theGratuity Plan") covering the eligible employees of the Company.
 The Gratuity Plan provides a lump-sum payment to vested
 employees at retirement, death, incapacitation or termination of
 employment, of an amount based on the respective employee's
 salary and the tenure of the employment with the Company.
 Liability with regard to the Gratuity Plan are determined byactuarial valuation, performed by an independent actuary, at
 each balance sheet date using the projected unit credit method.
 The defined benefit plan is administered by a trust formed for this
 purpose through the Company gratuity scheme.
 The Company recognises the net obligation of a defined benefitplan as a liability in its balance sheet. Gains or losses through re¬
 measurement of the net defined benefit liability are recognised
 in other comprehensive income and are not reclassified to
 profit and loss in the subsequent periods. The actual return of
 the portfolio of plan assets, in excess of the yields computed by
 applying the discount rate used to measure the defined benefit
 obligation is recognised in other comprehensive income. The
 effect of any plan amendments are recognised in the statement
 of profit and loss.
 Provident Fund Eligible employees of the Company receive benefits fromprovident fund, which is a defined contribution plan. Both
 the eligible employees and the Company make monthly
 contributions to the Government administered provident
 fund scheme equal to a specified percentage of the eligible
 employee's salary. Amounts collected under the provident fund
 plan are deposited with in a government administered provident
 fund. The Company has no further obligation to the plan beyond
 its monthly contributions. Company's contribution to the
 provident fund is charged to Statement of Profit and Loss.
 iii. Compensated absences: The Company has a policy on compensated absences whichare both accumulating and non-accumulating in nature. The
 expected cost of accumulating compensated absences is
 determined by actuarial valuation performed by an independent
 actuary at each balance sheet date using the projected unit credit
 method on the additional amount expected to be paid/availed
 as a result of the unused entitlement that has accumulated at the
 balance sheet date. Expense on non-accumulating compensated
 absences is recognised is the period in which the absences occur.
 The liability in respect of all defined benefit plans and other longterm benefits is accrued in the books of account on the basis
 of actuarial valuation carried out by an independent actuary
 using the Projected Unit Credit Method. The obligation is
 measured at the present value of estimated future cash flows.
 The discount rates used for determining the present value of
 obligation under defined benefit plans, is based on the market
 yields on Government securities as at the Balance Sheet date,
 having maturity periods approximating to the terms of related
 obligations.
 Remeasurement gains and losses on other long term benefitsare recognised in the Statement of Profit and Loss in the year in
 which they arise. Remeasurement gains and losses in respect of
 all defined benefit plans arising from experience adjustments and
 changes in actuarial assumptions are recognised in the period
 in which they occur, directly in other comprehensive income.They are included in other equity in the Statement of Changes in
 Equity and in the Balance Sheet. Changes in the present value of
 the defined benefit obligation resulting from plan amendments
 or curtailments are recognised immediately in profit or loss as
 past service cost. Gains or losses on the curtailment or settlement
 of any defined benefit plan are recognised when the curtailment
 or settlement occurs. Any differential between the plan assets
 (for a funded defined benefit plan) and the defined benefit
 obligation as per actuarial valuation is recognised as a liability if it
 is a deficit or as an asset if it is a surplus (to the extent of the lower
 of present value of any economic benefits available in the form of
 refunds from the plan or reduction in future contribution to the
 plan).
 Past service cost is recognised as an expense in the Statementof Profit and Loss on a straight-line basis over the average period
 until the benefits become vested. To the extent that the benefits
 are already vested immediately following the introduction
 of, or changes to, a defined benefit plan, the past service cost
 is recognised immediately in the Statement of Profit and Loss.
 Past service cost may be either positive (where benefits are
 introduced or improved) or negative (where existing benefits are
 reduced).
 iv. Share-based compensation The grant date fair value of equity settled share-based paymentawards granted to employees is recognised as an employee
 expense, with a corresponding increase in equity, over the
 period that the employees unconditionally become entitled to
 the awards. The amount recognised as expense is based on the
 estimate of the number of awards for which the related service
 and non-market vesting conditions are expected to be met, such
 that the amount ultimately recognised as an expense is based on
 the number of awards that do meet the related service and non¬
 market vesting conditions at the vesting date.
 The grant date fair value of options granted (net of estimatedforfeiture) to employees of the Company is recognised as an
 employee expense.
 The Company has adopted the policy to account for EmployeesWelfare Trust as a legal entity separate from the Company but as
 a subsidiary of the Company. Any loan from the Company to the
 trust is accounted for as a loan in accordance with its term.
 The expense is recorded for each separately vesting portion ofthe award as if the award was, in substance, multiple awards.
 The increase in equity recognised in connection with share based
 payment transaction is presented as a separate component
 in equity under "share based payment reserve". The amount
 recognised as an expense is adjusted to reflect the actual
 number of stock options that vest. For the option awards, grant
 date fair value is determined under the option-pricing model
 (Black-Scholes-Merton). Forfeitures are estimated at the time of
 grant and revised, if necessary, in subsequent periods if actual
 forfeitures materially differ from those estimates.
