 accordance with the Generally Accepted Accounting Principles in india
 (indian GAAP) to comply with the Accounting standards notified under
 the companies (Accounting standards) Rules, 2006 (as amended) and the
 relevant provisions of the companies Act, I956. The financial
 statements have been prepared on accrual basis under the historical
 cost convention. The accounting policies adopted in the preparation of
 the financial statements are consistent with those followed in the
 previous year.
 
 (ii) use of estimates
 
 The preparation of the financial statements in conformity with indian
 GAAP requires the Management to make estimates and assumptions
 considered in the reported amounts of assets and liabilities (including
 contingent liabilities) and the reported income and expenses during the
 year. The Management believes that the estimates used in preparation of
 the financial statements are prudent and reasonable. Future results
 could differ due to these estimates and the differences between the
 actual results and the estimates are recognised in the periods in which
 the results are known/ materialise.
 
 (iii) inventories
 
 inventories are valued at the lower of cost and moving weighted average
 price and the net realisable value after providing for obsolescence and
 other losses, where considered necessary. cost includes all charges in
 bringing the goods to the point of sale, including octroi and other
 levies, transit insurance and receiving charges. Work-in-progress and
 finished goods include appropriate proportion of overheads and, where
 applicable, excise duty.
 
 (iv) Depreciation and amortisation
 
 Depreciation has been provided on the straight-line method as per the
 rates prescribed in schedule XiV to the companies Act, I956.
 
 Assets costing less than Rs. 5,000 each are fully depreciated in the
 year of capitalisation.
 
 Depreciation on addition to fixed assets is provided on pro-rata basis
 from the month the assets are put to use.  Depreciation on
 sale/deduction from fixed assets is provided for up to the previous
 month of sale, deduction, discardment as the case may be.
 
 intangible assets comprising of product design, prototypes, etc.,
 either acquired or internally developed are amortised over a period of
 ten years, the estimated minimum useful life of the related products.
 cost of software is amortised over a period of 5 years or less
 depending on the estimated useful life of asset.
 
 The estimated useful life of the intangible assets and the amortisation
 period are reviewed at the end of each financial year and the
 amortisation method is revised to reflect the changed pattern.
 
 (v) Revenue recognition
 
 sales are recognised, net of returns and trade discounts, on transfer
 of significant risks and rewards of ownership to the buyer, which
 generally coincides with the dispatch of goods to customers. sales
 include excise duty but exclude sales tax and value added tax. Revenues
 from maintenance contracts are recognised pro-rata over the period of
 the contract.
 
 interest income is recognised on a time proportionate basis taking into
 account the amount invested and rate applicable.  Dividend income is
 accounted for when the right to receive it is established.
 
 (vi) Tangible fixed assets
 
 Fixed assets are carried at cost less accumulated depreciation and
 impairment losses, if any. The cost of fixed assets includes interest
 on borrowings attributable to acquisition of qualifying fixed assets up
 to the date the asset is ready for its intended use and other
 incidental expenses incurred up to that date. subsequent expenditure
 relating to fixed assets is capitalised only if such expenditure
 results in an increase in the future benefits from such asset beyond
 its previously assessed standard of performance.
 
 Fixed assets acquired and put to use for project purpose are
 capitalised and depreciation thereon is included in the project cost
 till commissioning of the project.
 
 capital work-in-progress:
 
 Projects under which assets are not ready for their intended use and
 other capital work-in-progress are carried at cost, comprising direct
 cost, related incidental expenses and attributable interest.
 
 Pre-operative expenditure (pending allocation):
 
 Expenses directly related to construction activity or incidental
 thereto, are allocated to fixed assets at the time of completion of the
 project.
 
 (vii) intangible assets
 
 intangible assets are carried at cost less accumulated amortisation and
 impairment losses, if any. The cost of an intangible asset comprises
 its purchase price, including any import duties and other taxes (other
 than those subsequently recoverable from the taxing authorities), and
 any directly attributable expenditure on making the asset ready for its
 intended use and net of any trade discounts and rebates. subsequent
 expenditure on an intangible asset after its purchase/completion is
 recognised as an expense when incurred unless it is probable that such
 expenditure will enable the asset to generate future economic benefits
 in excess of its originally assessed standards of performance and such
 expenditure can be measured and attributed to the asset reliably, in
 which case such expenditure is added to the cost of the asset.
 
 (viii) Foreign currency transactions
 
 Transactions denominated in foreign currencies are recorded at the
 exchange rates prevailing on the date of the transaction.
 
 Monetary items denominated in foreign currencies at the year-end are
 translated at the exchange rates prevailing on the Balance sheet date.

 Any income or expense on account of exchange differences either on
 settlement or on translation of transactions are charged to the
 statement of Profit and Loss.
 
 (ix) investments
 
 Long term investments are carried individually at cost, less provision
 for diminution, other than temporary, in the value of such investments.

 brokerage, fees and duties.
 
 (x) Employee benefits
 
 Employee benefits includes gratuity, compensated absences and
 contribution to provident fund, employees'' state insurance,
 superannuation fund.
 
 Defined contribution plans
 
 The company''s contribution to provident fund, employees'' state
 insurance, superannuation fund are considered as defined contribution
 plans and are charged as an expense as they fall due based on the
 amount of contribution required to be made. in respect of certain
 employees, provident fund contributions are made to a Trust where the
 interest rate payable to the members of such Trust shall not be lower
 than the statutory rate of interest declared by the central Government
 under the Employees Provident Funds and Miscellaneous Provisions Act,
 I952 and shortfall, if any, shall be made good by the company. The
 remaining contributions are made to a government administered provident
 fund towards which the company has no further obligations beyond its
 monthly contributions.
 
 Defined benefit plans
 
 For defined benefit plans in the form of gratuity, the cost of
 providing benefits is determined using the Projected Unit credit
 method, with actuarial valuations being carried out at each Balance
 sheet date. Actuarial gains and losses are recognised in the statement
 of Profit and Loss in the period in which they occur. Past service cost
 is recognised immediately to the extent that the benefits are already
 vested. The retirement benefit obligation recognised in the Balance
 sheet represents the present value of the defined benefit obligation as
 adjusted for unrecognised past service cost.
 
 Long-term employee benefits
 
 compensated absences which are not expected to occur within twelve
 months after the end of the period in which the employee renders the
 related service are recognised as a liability at the present value of
 the defined benefit obligation as at the Balance sheet date. The cost
 of providing benefits is determined using the Projected Unit credit
 method, with actuarial valuations being carried out at each Balance
 sheet date and actuarial gains and losses are recognised in the
 statement of Profit and Loss in the period in which they occur.

 incurred and exchange differences arising from foreign currency
 borrowings to the extent they are regarded as an adjustment to the
 interest cost. costs in connection with the borrowing of funds to the
 extent not directly related to the acquisition of qualifying assets are
 charged to the statement of Profit and Loss over the tenure of the
 loan. Borrowing costs, allocated to and utilised for qualifying assets,
 pertaining to the period from commencement of activities relating to
 construction/development of the qualifying asset upto the date of
 capitalisation of such asset is added to the cost of the assets.
 capitalisation of borrowing costs is suspended and charged to the
 statement of Profit and Loss during extended periods when active
 development activity on the qualifying assets is interrupted.
 
 (xiii) Earnings per share
 
 Basic earnings per share is computed by dividing the profit after tax
 by the weighted average number of equity shares outstanding during the
 year.
 
 Diluted earnings per share is computed by dividing the profit after tax
 as adjusted for dividend, interest and other charges to expense or
 income relating to the dilutive potential equity shares, by the
 weighted average number of equity shares considered for deriving basic
 earnings per share and the weighted average number of equity shares
 which could have been issued on the conversion of all dilutive
 potential equity shares.
 
 (xiv) income taxes
 
 current tax is the amount of tax payable on the taxable income for the
 year as determined in accordance with the provisions of the income Tax
 Act, I96I. The provision for taxation for the year ended December 3I,
 20I2 comprises the residual tax liability for the assessment year
 20I2-I3 relevant to the year April I, 20II to March 3I, 20I2 and the
 liability, which has accrued on the profit for the period April I, 20I2
 to December 3I, 20I2, under the provisions of the income-tax Act, I96I.
 
 Minimum Alternate Tax (MAT) paid in accordance with the tax laws, which
 gives future economic benefits in the form of adjustment to future
 income tax liability, is considered as an asset if there is convincing
 evidence that the company will pay normal income tax. Accordingly, MAT
 is recognised as an asset in the Balance sheet when it is probable that
 future economic benefit associated with it will flow to the company.
 
 Deferred tax is recognised on timing differences, being the differences
 between the taxable income and the accounting income that originate in
 one period and are capable of reversal in one or more subsequent
 periods. Deferred tax is measured using the tax rates and the tax laws
 enacted or substantially enacted as at the reporting date. Deferred tax
 liabilities are recognised for all timing differences. Deferred tax
 assets in respect of unabsorbed depreciation and carry forward of
 losses are recognised only if there is virtual certainty that there
 will be sufficient future taxable income available to realise such
 assets. Deferred tax assets are recognised for timing differences of
 other items only to the extent that reasonable certainty exists that
 sufficient future taxable income will be available against which these
 can be realised.
 
 (xv) Research and development expenses
 
 Revenue expenditure pertaining to research is charged to the statement
 of Profit and Loss. Development costs of products are also charged to
 the statement of Profit and Loss unless a product''s technological
 feasibility has been established, in which case such expenditure is
 capitalised. The amount capitalised comprises expenditure that can be
 directly attributed or allocated on a reasonable and consistent basis
 to creating, producing and making the asset ready for its intended use.
 Fixed assets utilised for research and development are capitalised and
 depreciated in accordance with the policies stated for Tangible Fixed
 Assets and intangible Assets.
 
 (xvi) Impairment of assets
 
 The carrying values of assets/cash generating units at each Balance
 sheet date are reviewed for impairment. if any indication of impairment
 exists, the recoverable amount of such assets is estimated and
 impairment is recognised, if the carrying amount of these assets
 exceeds their recoverable amount. The recoverable amount is the greater
 of the net selling price and their value in use. Value in use is
 arrived at by discounting the future cash flows to their present value
 based on an appropriate discount factor. When there is indication that
 an impairment loss recognised for an asset in earlier accounting
 periods no longer exists or may have decreased, such reversal of
 impairment loss is recognised in the statement of Profit and Loss.
 
 (xvii) Provisions and contingencies
 
 A provision is recognised when the company has a present obligation as
 a result of past events and it is probable that an outflow of resources
 will be required to settle the obligation in respect of which a
 reliable estimate can be made.  Provisions (excluding retirement
 benefits) are not discounted to their present value and are determined
 based on the best estimate required to settle the obligation at the
 Balance sheet date. These are reviewed at each Balance sheet date and
 adjusted to reflect the current best estimates. contingent liabilities
 are disclosed in the Notes.
 
 (xviii) Employee share based payments
 
 The company has formulated Employee stock Option scheme (EsOs) in
 accordance with the sEBi (Employee stock Option scheme and Employee
 stock Purchase scheme) Guidelines, I999. The scheme provides for grant
 of options to employees of the company and its subsidiaries to acquire
 equity shares of the company that vest in a graded manner and that are
 to be exercised within a specified period. in accordance with the sEBi
 Guidelines, the company has constituted an Employee stock Option Plan -
 2006. Employee stock Options granted by the company are accounted under
 the ''instrinsic Value Method'' stated in the Guidance Note on Employee
 share Based Payments issued by the institute of chartered Accountants
 of india.
 
 (xix) Provision for warranty
 
 The estimated liability for product warranties is recorded when
 products are sold. These estimates are established using historical
 information on the nature, frequency and average cost of warranty
 claims and management estimates regarding possible future incidence
 based on corrective actions on product failures. The timing of outflows
 will vary as and when warranty claim will arise.
 
 As per the terms of the contracts, the company provides post-contract
 services/warranty support to some of its customers. The company
 accounts for the post-contract support/provision for warranty on the
 basis of the information available with the Management duly taking into
 account the current and past technical estimates.
