a.  Basis of Preparation of Financial Statements
 
 These financial statements have been prepared under the historical cost
 convention from the books of accounts maintained on accrual basis in
 conformity with accounting principles generally accepted in India and
 comply with the Accounting Standards notified under Section 211 (3C) of
 the Companies Act, 1956 (the Act) and the relevant provisions of the
 Act.
 
 b.  Revenue Recognition
 
 Sales are accounted for inclusive of excise duty but excluding sales
 tax and trade discounts. Sales are recognised when the property and all
 significant risks and rewards of ownership are transferred to the buyer
 and no significant uncertainty exists regarding the amount of
 consideration that is derived from the sale of goods.
 
 Revenues in respect of long term contracts are recognised based on the
 percentage of completion method. However, provisions are made for
 anticipated losses (if any) for contracts to be completed in future.
 The percentage completion is determined based on the actual costs
 vis-a-vis the estimated total cost of a contract.  Interest Income is
 accounted on accrual basis and dividend income is accounted when right
 to receive payment is established.
 
 c.  Fixed Assets and Depreciation
 
 Fixed Assets are stated at cost, except for certain assets at Ambattur
 and Halol, which are stated at revalued figures. Surplus arising on
 revaluation of such assets is credited to revaluation reserve.
 Depreciation on revaluated portion is reduced from the revaluation
 reserve.
 
 Cost comprises the purchase price and any attributable cost of bringing
 the asset to its working condition for its intended use.
 
 Depreciation on building acquired up to March 31, 1984 is provided on
 the written down value method at rates prescribed under Schedule XIV to
 the Act.
 
 Depreciation on building acquired after March 31,1984 is provided on
 the straight-line method at the rates prescribed in Schedule XIV to the
 Act.
 
 Depreciation on other fixed assets is provided on straight line method
 as follows:

 Plant and Machinery                                                10
 Electrical Installations                                           10
 Computers                                                       33.34

 Leasehold Land is amortised over the period of the Lease.
 
 The above rates are based on technical estimates, approved by the
 Management, of the useful lives of the respective fixed assets, and are
 higher than the rates prescribed under Schedule XIV to the Act.
 Further, assets individually costing Rs. 5,000 or less are fully
 depreciated in the year of purchase.
 
 d.  Impairment of Fixed Assets
 
 The Company assesses at each Balance Sheet date whether there is any
 indication that an asset may be impaired. If any such indication
 exists, the Company estimates the recoverable amount of the asset. If
 such recoverable amount of the asset or recoverable amount of the
 cash-generating unit to which the asset belongs is less than its
 carrying amount, the carrying amount is reduced to its recoverable
 amount. The reduction is treated as an impairment loss and is
 recognised as such. If at the Balance Sheet date there is an indication
 that a previously assessed impairment loss no longer exists, the
 recoverable amount is reassessed and the asset is reflected at the
 recoverable amount.
 
 e.  Investments
 
 Long-term investments are valued at cost. Provision for diminution is
 made to recognise decline, other than temporary, in the value of
 long-term investments.
 
 f.  Inventories
 
 Inventories are stated at cost or net realisable value, whichever is
 lower. Cost is arrived at on First-In-First-Out (FIFO) method and
 includes, where appropriate, manufacturing overheads and excise duty.

 h.  Foreign Currency Transactions

 reversal in one or more subsequent periods. Deferred tax assets arising
 on account of unabsorbed depreciation or carry forward of tax losses
 are recognised only to the extent that there is virtual certainty
 supported by convincing evidence that sufficient future tax income will
 be available against which such deferred tax assets can be realised.
 
 j.  Provision and Contingent Liabilities
 
 The Company recognises a provision when there is a present obligation
 as a result of a past event that probably requires an outflow of
 resources and a reliable estimate can be made of the amount of the
 obligation. A disclosure for a contingent liability is made when there
 is a possible obligation or present obligation that may, but probably
 will not, require an outflow of resources. Where there is a possible
 obligation or a present obligation that the likelihood of outflow of
 resources is remote, no provision or disclosure as specified in
 Accounting Standard 29 - Provisions, Contingent Liabilities and
 Contingent Assets is made.

 are substantially transferred to the lessee are classified as finance
 leases. Finance leases are capitalised at the estimated present value
 of the minimum lease payments. Each lease payment is allocated between
 the liability and finance charges so as to achieve a constant rate on
 the finance balance outstanding. The corresponding rental obligations,
 net of finance charges, are included in secured loans. The interest
 element of the finance charge is charged to the Profit and Loss Account
 over the lease period. Leased assets are being depreciated over the
 lease period.
