The financial statements are prepared under the historical cost
 convention (other than land and buildings which have been revalued) on
 the accrual basis of accounting and in accordance with accounting
 principles generally accepted in India and comply with the accounting
 standards notified by the Central Government of India, under the
 Companies (Accounting Standards) rules 2006 and relevant provisions of
 the Companies Act, 1956. The significant accounting policies are as
 follows:
 
 (a) Revenue recognition
 
 Revenue is recognised on shipment or on unconditional appropriation of
 goods in accordance with the terms of the sale, Sales are inclusive of
 excise duties and net of trade discounts, returns and sales tax. Export
 benefits are accounted for in the year of exports based on eligibility
 or when there is no uncertainty in receiving the amount, at the
 estimated realisable value / actual credit earned during the year.
 
 (b) Foreign currency transactions
 
 Transactions in foreign currencies are accounted at the monthly average
 / daily exchange rates. Monetary assets and liabilities outstanding at
 the year end are restated at the closing rates. Exchange differences
 arising on foreign currency transactions settled during the year /
 restated at the end of the year are recognised in the profit and loss
 account.
 
 In accordance with Accounting Standard AS-11 (Revised), The effects
 of changes in foreign exchange rates, the branches located outside
 India have been classified as Integral foreign operation and exchange
 differences on translation is charged to Profit & Loss account.
 
 The Company uses forward contracts to hedge its risks associated with
 foreign currency fluctuations relating to certain firm commitments and
 highly probable transactions. The use of forward contracts is governed
 by the Companys policies on the use of such financial derivatives
 consistent with the Companys risk management strategy. In cases where
 the Company has entered into forward exchange contracts, with
 underlying transactions, the difference between the forward rate and
 the initial spot rate is recognised as an income or expense over the
 life of the contract. Exchange gains/losses on intermediary forward
 contracts relating to firm commitments are recognised in the profit and
 loss account based on fair value changes as at the balance sheet date.
 Any profit or loss arising on cancellation of forward exchange
 contracts is recognised as income or expense for the year.  Cash flows
 arising on account of roll over of forward contracts are recognised as
 income/expense of the year.
 
 (c) Fixed assets and depreciation
 
 Fixed Assets are recorded at cost (except for the revalued land and
 buildings which are shown at estimated replacement cost as determined
 by the valuers) less accumulated depreciation. The Company capitalises
 all costs relating to acquisition and installation of fixed assets.
 Cost of special tools is capitalised as plant and machinery.
 
 Fixed assets, other than land, but including revalued buildings, are
 depreciated pro-rata to the period of use based on straight line method
 over the estimated useful lives of assets, at the following annual
 rates which are higher than the rates specified under Schedule XIV of
 the Companies Act, 1956, whererver applicable:
 
 Buildings /Leasehold improvements - 2.5%, 4.0% and 33.3%
 
 Plant and machinery - 10.0%, 20.0% and 33.3%

 Assets individually costing less than Rs 5,000 /- are fully depreciated
 in the year of addition.
 
 Leasehold land/improvements is depreciated over a period not exceeding
 that of the lease.
 
 The charge over and above the depreciation calculated on the original
 cost of the revalued assets is transferred from Fixed Asset Revaluation
 Reserve to the Profit and Loss Account.
 
 Direct expenditure on assets under construction or development is shown
 under Capital work-in-progress, while indirect expenditure is charged
 off.
 
 (d) Impairment of assets
 
 The Company determines whether there is any indication of impairment of
 the carrying amount of the Companys assets. The recoverable amount of
 such assets are estimated, if any indication exists, and impairment
 loss is recognised wherever the carrying amount of the assets exceeds
 its recoverable amount.
 
 (e) Research and development
 
 Revenue expenditure on research and development activities is expensed
 in the year in which it is incurred.
 
 (f) Technical know-how, testing and certification fees
 
 Technical know-how, testing and certification fee in respect of new
 products is expensed in the year in which it is incurred.
 
 (g) Inventories
 
 Inventories comprising of raw material, work in progress, finished
 goods and stores and spares are valued at lower of cost (net of Cenvat,
 where applicable) and net realisable value. Cost includes cost of
 purchase, cost of conversion and other costs incurred in bringing the
 inventories to their present location and condition. Cost in respect of
 raw materials and stores and spares is established using moving
 weighted average method. Cost of finished goods and work-in-progress,
 determined on moving weighted average method, includes all applicable
 manufacturing overheads. The value of finished goods includes excise
 duty payable on despatch. The inventories are stated net of write downs
 / allowances on account of obsolete, damaged and slow- moving items.
 
 (h) Investments
 
 Long term investments are stated at cost of acquisition. The
 diminution, if any, in the value of investments stated at cost, is
 recognised when such diminution is considered other than temporary.
 
 (i) Employee benefits
 
 i) Provident Fund : the contributions made to regional provident fund
 are expensed to profit and loss account as and when such contributions
 are due. In other cases the Company contributes to a recognized trust
 and contributions are expensed to Profit and loss when such amounts are
 due. The interest rate payable by the Trust to the beneficiaries every
 year is being notified by the Government. The Company has an obligation
 to make good the shortfall, if any, between the return from the
 investments of the Trust and the interest cost based on notification
 and recognizes such obligation as an expense.  Having regard to the
 assets of the Fund and the return on the investments, the Company does
 not expect any deficiency in the foreseeable future, in excess of the
 amount already provided for as per the management estimates.
 
 ii) Superannuation Fund: The Company makes contribution to a scheme
 administered by the Life Insurance Corporation of India (LIC) to
 discharge superannuating liabilities to the employees, a defined
 contribution plan, and the same is expensed to Profit and loss account.
 The company has no liability other than its annual contribution.
 
 iii) Gratuity: The Company makes contribution to a scheme administered
 by the Life Insurance Corporation of India (LIC) to discharge
 gratuity liabilities to the employees, a defined benefit plan. The
 Company accounts its liability for future gratuity payouts based on
 actuarial valuation, as at balance sheet date, determined by LIC using
 the projected unit credit method and are funded.
 
 In case of managerial employees in addition to the ceiling defined
 under the Gratuity Act, certain additional amounts are paid depending
 upon the period served for the company. This additional gratuity is
 also determined by an actuarial valuation as on the balance sheet date,
 but is not funded through a separate corpus. Effects of changes in
 actuarial valuations are immediately recognized in the profit and loss
 account.
 
 iv) Compensated leave : The Company records its liability on
 compensated leave based on actuarial valuation as at the balance sheet
 date, using the projected unit credit method. Effects of changes in
 actuarial valuations are immediately recognised in the profit and loss
 account. Short term employee benefits are recognised as an expense as
 per the companys scheme based on expected obligation on undiscounted
 basis.
 
 (j) Employee voluntary separation schemes
 
 Lump sum separation payouts are expensed when the scheme is accepted by
 an employee. In respect of schemes where payments are to be made for a
 longer period till the age of retirement or death of an employee,
 whichever is earlier, the liability is actuarially valued and charged
 to the profit and loss account in the year in which the scheme is
 accepted by an employee. In case of fixed term obligations, liabilities
 are valued at net present value. Interest component implicit in the
 payout during the period is expensed. Further, whenever a management
 decision is taken to restructure operations, the Company considers
 provision for estimated employee separation costs.
 
 (k) Long-term contracts
 
 Sales revenue and margins on construction contracts and certain
 services are recognized according to the percentage of completion
 method (PCM), as provided in AS 7 (Revised) - Construction
 contracts. Sales revenue and income from long- term contracts are
 recognized over the period of performance of the contract on
 achievement of certain internal milestones.  Depending on the contract
 terms,, the percentage of completion is determined based on costs or
 the stage of physical completion. Under the cost-based PCM formula, the
 stage of completion is equal to the ratio of costs to the total
 estimated cost of the contract.
 
 Under the physical completion PCM formula, a predetermined percentage
 of completion is assigned to each stage of completion of the contract.
 The sales revenue and costs recognized at the end of the period are
 equal to the percentage of sales revenue and anticipated costs for the
 stage of completion achieved at that date. Income recognition arising
 on these contracts are based on estimated overall profitability of
 individual contracts reviewed periodically. Direct costs incurred for
 long term contracts over and above the pro-rata to sales is considered
 as work-in-progress. Provision for expected loss is recognised
 immediately when it is probable that the total estimated contract costs
 will exceed total contract revenue, based on Managements analysis of
 the risks and exposures on a case to case basis.
 
 (I) Taxation
 
 Current tax is determined on the profit of the year in accordance with
 the provisions of Income Tax Act, 1961. Deferred tax is calculated at
 the tax rates and laws that have been enacted or substantively enacted
 by the Balance sheet date and is recognised on timing differences that
 originate in one period and are capable of reversal in one or more
 subsequent periods. Deferred tax assets, subject to consideration of
 prudence, are recognised and carried forward only to the extent that
 they can be realised.
 
 (m) Use of estimates
 
 The preparation of the financial statements in conformity with the
 generally accepted accounting principles requires estimates and
 assumptions to be made that affect the reported amount of assets and
 liabilities and the disclosures relating to contingent assets and
 liabilities as on the date of financial statements and the reported
 amount of revenues and expenses during the reporting period. Management
 believes that the estimates used in the preparation of financial
 statements are prudent and reasonable. Actual results could differ from
 these estimates.
 
 (n) Provisions, Contingent assets and liabilities
 
 Provisions involving substantial degree of estimation in measurement
 are recognised when there is a present obligation as a result of past
 events and it is probable that there will be an outflow of resources.
 Contingent liabilities are not recognized as a liability but are
 disclosed in the notes. Contingent assets are neither recognised nor
 disclosed in the financial statements.
