| 1.3 Material Accounting policies(A) Property, Plant and Equipment : Property, plant and equipment are carried at its cost,net of recoverable taxes, trade discounts and rebate less
 accumulated depreciation and impairment losses, if any. Cost
 includes purchase price, borrowing cost, non refundable taxes
 or levies and directly attributable cost of bringing the asset
 to its working condition for its intended use. Expenditure
 related to plans, designs and drawings of buildings or plant
 and machinery is capitalized under relevant heads of property,
 plant and equipment if the recognition criteria are met.
 Subsequent costs are included in the asset’s carrying amount
 or recognised as a separate asset, as appropriate, only when
 it is probable that future economic benefits associated withthe item will flow to the entity and the cost can be measured
 reliably. In case of Property, Plant and Equipment, the
 Company has availed the fair value as deemed cost on the date
 of transition i.e. April 01, 2016.
 Property, Plant and Equipment not ready for the intended useon the date of Balance Sheet are disclosed as “Capital Work-in¬
 Progress” and expenses incurred relating to it, net of income
 earned during the development stage, are disclosed as pre¬
 operative expenses under “Capital Work-in-Progress”.
 Property, Plant and Equipment are eliminated from StandaloneFinancial Statements, either on disposal or when retired from
 active use. Gains / losses arising in the case of retirement/
 disposal of Property, Plant and Equipment are recognised in
 the statement of profit and loss in the year of occurrence.
 Capital work in progress and Capital advances: Cost of assets not ready for intended use, as on the BalanceSheet date, is shown as capital work in progress. Advances
 given towards acquisition of property, plant and equipment
 outstanding at each Balance Sheet date are disclosed as Other
 Non-Current Assets.
 Depreciation: Depreciation on property, plant and equipment is providedon straight line method for the year for which the assets have
 been used as under:
 (a)    Depreciation on assets is provided over the useful life ofassets as prescribed under schedule II of Companies Act,
 2013 except Mobile phones where 3 years have been taken
 (b)    Leasehold land is amortised over the period of lease. The asset's residual values, useful lives and method ofdepreciation are reviewed at each financial year end and are
 adjusted prospectively, if appropriate.
 (B) Intangible Assets and Amortisation:Intangible Assets are stated at cost, net of accumulatedamortization and impairment losses, if any. Intangible assets
 are amortised on a straight line basis over their estimated useful
 lives. The amortisation period and the amortisation method
 are reviewed at least at each financial year end. If the expected
 useful life of the asset is significantly different from previous
 estimates, the amortisation period is changed accordingly.
 Gain or losses arising from the retirement or disposal of an
 intangible asset are determined as the difference between the
 net disposal proceeds and the carrying amount of the asset
 and recognized as income or expense in the Statement of
 Profit and Loss. In case of Intangible Assets, the Company has
 availed the fair value as deemed cost on the date of transition
 i.e. April 01, 2016.The period of amortisation is as under :
 (C)    Investment Property:Investment property is held for long term rental incomeand/or for capital appreciation. Investment properties are
 measured initially at cost, including transaction costs and net
 of recoverable taxes, trade discounts and rebates. Subsequent
 to initial recognition, investment properties are stated at cost
 less accumulated depreciation and impairment losses, if any.
 Depreciation on investment properties is provided usingstraight line method over the estimated useful lives as
 specified in Schedule II to the Companies Act, 2013. Residual
 values, useful lives and method of depreciation of investment
 properties are reviewed at each financial year end and are
 adjusted prospectively, if appropriate. The effects of any
 revision are included in the statement of profit and loss when
 the changes arises.
 Though the Company measures investment properties usingcost based measurement, the fair value of investment property
 is disclosed in the notes.
 Investment properties are derecognised either when they havebeen disposed off or when they are permanently withdrawn
 from use and no future economic benefit is expected from
 their disposal. The difference between the net disposal
 proceeds and the carrying amount of the asset is recognised in
 statement of profit and loss in the period of de-recognition.
 (D)    Impairment of Non-Financial Assets - Property, Plantand Equipment & Intangible Assets:
The Company assesses at each reporting date as to whetherthere is any indication that any property, plant and equipment
 and intangible assets or group of assets, called cash generating
 units (CGU) may be impaired. If any such indication exists the
 recoverable amount of an asset or CGU is estimated to determine
 the extent of impairment, if any. When it is not possible to
 estimate the recoverable amount of an individual asset, the
 Company estimates the recoverable amount of the CGU to
 which the asset belongs. An impairment loss is recognised in
 the Statement of Profit and Loss to the extent, asset’s carrying
 amount exceeds its recoverable amount. The impairment loss
 recognised in prior accounting period is reversed if there has
 been a change in the estimate of recoverable amount. The
 recoverable amount is higher of an asset’s fair value less cost of
 disposal and value in use. Value in use is based on the estimated
 future cash flows, discounted to their present value using pre¬
 tax discount rate that reflects current market assessments of the
 time value of money and risk specific to the assets.
 (E)    Taxes on Income:Tax expense represents the sum of current tax (includingincome tax for earlier years) and deferred tax. Tax is recognised
 in the statement of profit and loss, except to the extent that
 it relates to items recognised directly in equity or other
 comprehensive income, in such cases the tax is also recognised
 directly in equity or in other comprehensive income. Any
 subsequent change in direct tax on items initially recognised
 in equity or other comprehensive income is also recognised in
 equity or other comprehensive income.
 Current tax provision is computed for Income calculated afterconsidering allowances and exemptions under the provisions
 of the applicable Income Tax Laws. Current tax assets and
 current tax liabilities are off set, and presented as net.
 Deferred tax is recognised on differences between the carryingamounts of assets and liabilities in the Balance sheet and the
 corresponding tax bases used in the computation of taxable
 profit. Deferred tax liabilities are generally recognised for all
 taxable temporary differences, and deferred tax assets are
 generally recognised for all deductible temporary differences,
 carry forward tax losses and allowances to the extent that it
 is probable that future taxable profits will be available against
 which those deductible temporary differences, carry forward
 tax losses and allowances can be utilised. Deferred tax assets
 and liabilities are measured at the applicable tax rates. The
 carrying amount of deferred tax assets is reviewed at each
 Balance Sheet date and reduced to the extent that it is no
 longer probable that sufficient taxable profits will be available
 against which the temporary differences can be utilised.
 (F)    Inventories:Inventories are measured at lower of cost and net realisable value(NRV) after providing for obsolescence , if any. NRV is the estimate
 selling price in the ordinary course of business, less estimated
 costs of completion and estimate cost necessary to make the
 sale. Cost of Inventories comprises of cost of purchase, cost of
 conversion and other costs incurred in bringing them to their
 respective present location and condition. Cost of raw materials,
 stores & spares, packing materials are determined on weighted
 average basis. The Cost of Work in Progress and Finished Goods is
 determined on absorption costing methods.
 (G)    Financial Instruments:A financial instrument is any contract that gives rise to afinancial asset of one entity and a financial liability or equity
 instrument of another entity.
 Financial Assets -Initial recognition and measurement All financial assets are initially recognized at fair value.Transaction costs that are directly attributable to the
 acquisition of financial assets, which are not at fair value
 through profit or loss, are adjusted to the fair value on
 initial recognition. Financial assets are classified, at initialrecognition, as financial assets measured at fair value or as
 financial assets measured at amortised cost. Purchase and sale
 of financial assets are recognized using trade date accounting.
 However, trade receivables that do not contain a significant
 financing component are measured at transaction price.
 Financial assets - Subsequent measurement For the purpose of subsequent measurement financial assetsare classified in two broad categories:-
 a)    Financial assets at fair value b)    Financial assets at amortised cost Where assets are measured at fair value, gains and lossesare either recognised entirely in the statement of profit and
 loss (i.e. fair value through profit and loss), or recognised in
 other comprehensive income (i.e. fair value through other
 comprehensive income).
 A financial asset that meets the following two conditionsis measured at amortised cost (net of any write down for
 impairment) unless the asset is designated at fair value
 through profit or loss under the fair value option.
 a)    Business model test: The objective of the Company'sbusiness model is to hold the financial asset to collect
 the contractual cash flow.
 b)    Cash flow characteristics test: The contractual terms ofthe financial asset give rise on specified dates to cash
 flow that are solely payments of principal and interest on
 the principal amount outstanding.
 A financial asset that meets the following two conditions ismeasured at fair value through other comprehensive income
 unless the asset is designated at fair value through profit or
 loss under the fair value option.
 a)    Business model test: The financial asset is held withina business model whose objective is achieved by
 both collecting contractual cash flow and selling
 financial assets.
 b)    Cash flow characteristics test: The contractual terms ofthe financial asset give rise on specified dates to cash
 flow that are solely payments of principal and interest on
 the principal amount outstanding.
 All other financial asset is measured at fair value throughprofit or loss.
 Financial assets - Derecognition A financial assets (or, where applicable, a part of a financialasset or part of a group of similar financial assets) is primarily
 derecognised (i.e. removed from the Company's statement offinancial position) when:
 a)    The rights to receive cash flows from the assethave expired, or
 b)    The Company has transferred its rights to receive cashflow from the asset.
 Impairment of Financial Assets In accordance with Ind AS 109, the Company uses ‘ExpectedCredit Loss’ (ECL) model, for evaluating impairment of financial
 assets other than those measured at fair value through profit
 and loss (FVTPL).
 Expected credit losses are measured through a loss allowanceat an amount equal to:
 a)    The 12-months expected credit losses (expectedcredit losses that result from those default events on
 the financial instrument that are possible within 12
 months after the reporting date); or
 b)    Full lifetime expected credit losses (expected creditlosses that result from all possible default events over
 the life of the financial instrument)
 For trade receivables Company applies ‘simplified approach’which requires expected lifetime losses to be recognised
 from initial recognition of the receivables. The Company
 uses historical default rates to determine impairment loss
 on the portfolio of trade receivables. At every reporting date
 these historical default rates are reviewed and changes in the
 forward looking estimates are analysed.
 For other assets, the Company uses 12 month ECL to providefor impairment loss where there is no significant increase
 in credit risk. If there is significant increase in credit risk full
 lifetime ECL is used.
 Financial Liabilities - Initial recognition and measurement: The financial Liabilities are recognised initially at fair valueand, in the case of loans and borrowings and payables, net of
 directly attributable transaction costs.
 Financial Liabilities - Subsequent measurement: Financial Liabilities are subsequently carried at amortisedcost using the effective interest method. For trade and other
 payables maturing within one year from the Balance Sheet
 date, the carrying amounts approximate fair value due to the
 short maturity of these instruments.
 Financial Liabilities - Financial guarantee contracts: Financial guarantee contracts issued by the Companyare those contracts that require a payment to be made to
 reimburse the holder for a loss it incurs because the specified
 debtor fails to make a payment when due in accordance withthe terms of a debt instrument. Financial guarantee contracts
 are recognised initially as a liability at fair value, adjusted for
 transaction costs that are directly attributable to the issuance
 of the guarantee. Subsequently, the liability is measured at the
 higher of the amount of loss allowance determined and the
 amount recognised less cumulative amortisation.
 Financial liability - Derecognition: A financial liability is derecognised when the obligation underthe liability is discharged or cancelled or expires. When an
 existing financial liability is replaced by another, from the
 same lender on substantially different terms, or the terms of an
 existing liability are substantially modified, such an exchange
 or modification is treated as the derecognition of the original
 liability and the recognition of a new liability. The difference in
 the respective carrying amounts is recognised in the statement
 of profit and loss.
 (H) Fair Value:The Company measures financial instruments at fair valueat each Balance sheet date. Fair value is the price that would
 be received to sell an asset or paid to transfer a liability in
 an orderly transaction between market participants at the
 measurement date. The fair value measurement is based
 on the presumption that the transaction to sell the asset or
 transfer the liability takes place either:
 -    in the principal market for the asset or liability, or -    in the absence of a principal market, in the mostadvantageous market for the asset or liability
 All assets and liabilities for which fair value is measuredor disclosed in the Standalone Financial Statements are
 categorized within the fair value hierarchy that categorizes
 into three levels, described as follows, the inputs to valuation
 techniques used to measure value. The fair value hierarchy
 gives the highest priority to quoted prices in active markets
 for identical assets or liabilities (Level 1 inputs) and the lowest
 priority to unobservable inputs (Level 3 inputs).
 Level 1 — quoted (unadjusted) market prices in active marketsfor identical assets or liabilities
 Level 2 — inputs other than quoted prices included withinLevel 1 that are observable for the asset or liability, either
 directly or indirectly
 Level 3 — inputs that are unobservable for the asset or liability For assets and liabilities that are recognized in the StandaloneFinancial Statements at fair value on a recurring basis, the
 Company determines whether transfers have occurred
 between levels in the hierarchy by re-assessing categorization
 at the end of each reporting period and discloses the same.
 (I)    Investment in Subsidiaries and Associates:The Company has elected to recognize its investmentsin subsidiaries and associate at cost in accordance with
 the option available in Ind AS 27, ‘Separate Standalone
 Financial Statements’.
 (J)    Revenue Recognition and Other Income:Sales of goods and services: The Company derives revenues primarily from sale of productscomprising of Defence & Space Applications
 Revenue from contracts with customers is recognisedwhen control of the goods or services are transferred to the
 customer at an amount that reflects the consideration entitled
 in exchange for those goods or services. Generally, control is
 transferred upon shipment of goods to the customer or when
 the goods is made available to the customer, provided transfer
 of title to the customer occurs and the Company has not
 retained any significant risks of ownership or future obligations
 with respect to the goods shipped.
 Revenue is measured at the amount of consideration which thecompany expects to be entitled to in exchange for transferring
 distinct goods or services to a customer as specified in the
 contract, excluding amounts collected on behalf of third
 parties (for example taxes and duties collected on behalf of the
 government). Consideration is generally due upon satisfaction
 of performance obligations and a receivable is recognized
 when it becomes unconditional.
 The Company does not expect to have any contracts where theperiod between the transfer of the promised goods or services
 to the customer and payment by the customer exceeds one
 year. As a consequence, it does not adjust any of the transaction
 prices for the time value of money.
 Revenue is measured based on the transaction price, which isthe consideration, adjusted for volume discounts, performance
 bonuses, price concessions and incentives, if any, as specified
 in the contract with the customer. Revenue also excludes taxes
 collected from customers.
 Revenue from rendering of services is recognised over timeby measuring the progress towards complete satisfaction of
 performance obligations at the reporting period.
 Contract Balances - Trade Receivables A receivable represents the Company’s right to an amount ofconsideration that is unconditional.
 Contract liabilities A contract liability is the obligation to transfer goods orservices to a customer for which the Company has received
 consideration (or an amount of consideration is due) from the
 customer. If a customer pays consideration before the Company
 transfers goods or services to the customer, a contract liabilityis recognised when the payment is made or the payment is
 due (whichever is earlier). Contract liabilities are recognised as
 revenue when the Company performs under the contract.
 Other Income: Incentives on exports and other Government incentives relatedto operations are recognised in the statement of profit and loss
 after due consideration of certainty of utilization/receipt of
 such incentives.
 Interest Income: Interest income from a financial asset is recognised whenit is probable that the economic benefits will flow to the
 Company and the amount of income can be measured reliably.
 Interest income is accrued on a timely basis, by reference to
 the principal outstanding and at the effective interest rate
 applicable, which is the rate that exactly discounts estimated
 future cash receipts through the expected life of the financial
 asset to that asset’s net carrying amount on initial recognition.
 Dividend Income: Dividend Income is recognised when the right to receive thepayment is established.
 Rental income: Rental income arising from operating leases is accounted foron a straight-line basis over the lease terms and is included as
 other income in the statement of profit or loss.
 (K) Foreign currency transactions and translation:Transactions in foreign currencies are recorded at the exchangerate prevailing on the date of transaction. Monetary assets and
 liabilities denominated in foreign currencies are translated
 at the functional currency closing rates of exchange at the
 reporting date.
 Exchange differences arising on settlement or translation ofmonetary items are recognised in Statement of Profit and Loss
 except to the extent of exchange differences which are regarded
 as an adjustment to interest costs on foreign currency borrowings
 that are directly attributable to the acquisition or construction of
 qualifying assets, are capitalized as cost of assets.
 Non-monetary items that are measured in terms of historicalcost in a foreign currency are translated using the exchange
 rates at the dates of the transaction. Non-monetary items
 carried at fair value that are denominated in foreign currencies
 are translated at the exchange rates prevailing at the date
 when the fair value was determined. The gain or loss arising
 on translation of non-monetary items measured at fair value
 is treated in line with the recognition of the gain or loss on the
 change in fair value of the item (i.e., translation differences on
 items whose fair value gain or loss is recognised in OCI or profit
 or loss are also recognised in OCI or profit or loss, respectively).
 Foreign exchange differences regarded as an adjustment toborrowing costs are presented in the statement of profit and
 loss, within finance costs. All other finance gains / losses are
 presented in the statement of profit and loss on a net basis.
 In case of an asset, expense or income where a monetaryadvance is paid/received, the date of transaction is the date
 on which the advance was initially recognized. If there were
 multiple payments or receipts in advance, multiple dates of
 transactions are determined for each payment or receipt of
 advance consideration.
 (L)    Employee Benefits:Short term employee benefits are recognized as an expensein the statement of profit and loss of the year in which the
 related services are rendered. Contribution to Provident Fund,
 a defined contribution plan, is made in accordance with the
 statute, and is recognised as an expense in the year in which
 employees have rendered services.
 The cost of providing gratuity, a defined benefit plans, isdetermined based on Projected Unit Credit Method, on the
 basis of actuarial valuations carried out by third party actuaries
 at each Balance Sheet date. Actuarial gains and losses arising
 from experience adjustments and changes in actuarial
 assumptions are charged or credited to other comprehensive
 income in the period in which they arise. Other costs are
 accounted in statement of profit and loss.
 Remeasurements of defined benefit plan in respect of postemployment and other long term benefits are charged to the
 other comprehensive income in the year in which they occur.
 Remeasurements are not reclassified to statement of profit
 and loss in subsequent periods.
 (M)    Share based paymentsThe cost of equity-settled transactions with employees ismeasured at fair value at the date at which they are granted.
 The fair value of share options are determined with the
 assistance of an external valuer and the fair value at the grant
 date is expensed on a proportionate basis over the vesting
 period based on the Company’s estimate of shares that will
 eventually vest. The estimate of the number of options likely
 to vest is reviewed at each balance sheet date up to the vesting
 date at which point the estimate is adjusted to reflect the
 current expectations.
