| 2. MATERIAL ACCOUNTING POLICY INFORMATION2.1 Basis of preparation
These standalone Ind AS financial statements have beenprepared in accordance with Indian Accounting Standards
 (Ind AS) notified under the Companies (Indian Accounting
 Standards) Rules, 2015 (as amended from time to time) and
 presentation requirements of Division II of Schedule III to the
 Companies Act, 2013 (Ind AS compliant Schedule III).
 Accounting policies have been consistently applied except
 where a newly issued accounting standard is initially adopted
 or a revision to an existing accounting standard requires a
 change in the accounting policy hitherto in use.
 The standalone Ind AS financial statements are presentedin Rs. and all values are rounded to the nearest Lacs (Rs.
 00,000), except when otherwise indicated.
 The standalone Ind AS financial statements providecomparative information in respect of the previous year.
 Basis of measurementThe standalone Ind AS financial statements have beenprepared on historical cost basis, except for the following
 assets and liabilities which have been measured at fair value
 as required under relevant Ind AS.
 -    Certain financial assets and liabilities are measured atfair value (Refer accounting policy regarding financial
 instruments in Note o)
 -    Defined benefit plans - plan assets are measured at fairvalue
 a.    Current versus non-current classificationBased on the time involved between the acquisition ofassets for processing and their realization in cash and
 cash equivalents, the Company has identified twelve
 months as its operating cycle for determining current
 and non-current classification of assets and liabilities in
 the balance sheet. Deferred tax assets and liabilities are
 classified as non-current assets and liabilities.
 b.    Investment in subsidiaries, associate and jointventure
A subsidiary is an entity that is controlled by anotherentity.
 An associate is an entity over which the Company hassignificant influence. Significant influence is the power
 to participate in the financial and operating policy
 decisions of the investee but is not control or joint
 control over those policies.
 A joint venture is a type of joint arrangement wherebythe parties that have joint control of the arrangement
 have rights to the net assets of the joint venture. Joint
 control is the contractually agreed sharing of control
 of an arrangement, which exists only when decisions
 about the relevant activities require unanimous consent
 of the parties sharing control.
 The Company's investments in its subsidiaries,associates and joint ventures are accounted at cost less
 impairment.
 Impairment of investmentsThe Company reviews its carrying value of investmentscarried at cost annually, or more frequently when there
 is indication for impairment. If the recoverable amount
 is less than its carrying amount, the impairment loss is
 recorded in the Statement of Profit and Loss.
 When an impairment loss subsequently reverses, thecarrying amount of the Investment is increased to the
 revised estimate of its recoverable amount, so that the
 increased carrying amount does not exceed the cost
 of the Investment. A reversal of an impairment loss is
 recognised immediately in Statement of Profit or Loss.
 c.    Property, plant and equipment ('PPE')Recognition and measurementProperty, plant and equipment are stated at costnet of accumulated depreciation and accumulated
 impairment losses, if any.
 Cost of an item of PPE comprises its purchase price,including import duties and non-refundable purchase
 taxes, after deducting trade discounts and rebates,
 any directly attributable cost of bringing the item to
 its working condition for its intended use. The cost
 of a self-constructed item of property, plant and
 equipment comprises the cost of materials and direct
 labour, 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, if the
 recognition criteria is met. 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.
 Capital work-in-progress is stated at cost, net of
 accumulated impairment loss, if any. Property, plant
 and equipment are stated at cost of acquisition or
 construction which includes capitalised finance costs
 less accumulated depreciation and accumulated
 impairment loss, if any.
 Recognition criteriaThe cost of an item of property, plant and equipment isrecognised as an asset if and only if,
 (a)    It is probable that future economic benefitsassociated with the item will flow to the entity,
 and
 (b)    The cost of the item can be measured reliably.Capital work-in-progress comprises the cost of
 property, plant and equipment that are not ready
 for their intended use at the reporting date, net of
 accumulated impairment loss, if any. Advances paid
 towards acquisition of PPE outstanding at each balance
 sheet date, are shown under other non-current assets.
 Any gain or loss on disposal of an item of property, plantand equipment is recognised in the Statement of Profit
 and Loss.
 Subsequent expenditureSubsequent expenditure is capitalised only if it isprobable that the future economic benefits associated
 with the expenditure will flow to the Company and its
 cost can be measured reliably with the carrying amount
 of the replaced part getting derecognised.
 DepreciationDepreciation is calculated on cost of items of PPE lesstheir estimated residual values over their estimated
 useful lives using the straight-line method and is
 recognised in the Statement of Profit and Loss.
 
Depreciation on improvements carried out on buildingstaken on lease is provided over the period of the lease
 or useful life of assets, whichever is lower. Refer lease
 policy at point 'n' below for period of leases.
 *The Company, based on technical assessment madeby technical expert and management estimate,
 depreciates tools included in plant and equipment
 over estimated useful lives of 3 and 15 years which are
 different from the useful life prescribed in Schedule II
 to the Companies Act, 2013. The management believes
   that these estimated useful lives are realistic and reflectfair approximation of the period over which the assets
 are likely to be used.
 The depreciation method, useful lives and residualvalues are reviewed at each financial year-end and
 adjusted if appropriate.
 Depreciation on additions (disposal) is provided on apro-rata basis i.e. from (upto) the date on which asset is
 ready for use (disposed of).
 DerecognitionAn item of property, plant and equipment isderecognised upon disposal or when no future
 economic benefits are expected from its use and
 disposal. Any gain or loss arising on derocogntion of the
 asset is measured as the difference between the net
 disposal proceeds and the carrying amount of the asset
 and is recognised in the Statement of Profit and Loss.
 d. Intangible assetsAcquired IntangibleIntangible assets that are acquired by the Companyare measured initially at cost. Cost of an item of
 Intangible asset comprises its purchase price, including
 import duties and non-refundable purchase taxes,
 after deducting trade discounts and rebates, any
 directly attributable cost of bringing the item to its
 working condition for its intended use. After initial
 recognition, an intangible asset is carried at its cost less
 any accumulated amortisation and any accumulated
 impairment loss.
 AmortisationAmortisation is calculated to write off the cost ofintangible assets over their estimated useful lives using
 the straight-line method, and is included in depreciation
 and amortisation expense in Statement of Profit and
 Loss.
 The estimated useful lives are as follows: -    Technical know-how    4 Years -    Software    6 Years Amortisation method, useful life and residual values arereviewed at the end of each financial year and adjusted
 if appropriate.
 DerecognitionIntangible assets are derecognised on disposal or whenno future economic benefits are expected from its use
 and disposal. Any gain or loss arising upon derecognition
 of the asset (calculated as the difference between the
 net disposal proceeds and the carrying amount of the
 asset) is included in the statement of profit and loss
 when the asset is derecognised.
 Intangible asset under development that are acquiredby the Company comprises its purchase price, including
 import duties and non-refundable purchase taxes, after
 deducting trade discounts and rebates, any directly
 attributable cost of bringing the item to its working
 condition for its intended use.
 Research and development costsResearch costs are expensed as incurred. Developmentexpenditures on an individual project are recognised
 as an intangible asset when the Company can
 demonstrate:
 >    The technical feasibility of completing theintangible asset so that the asset will be available
 for use or sale
 >    Its intention to complete and its ability andintention to use or sell the asset
 >    How the asset will generate future economicbenefits
 >    The availability of resources to complete the asset >    The ability to measure reliably the expenditureduring development
 Following initial recognition of the developmentexpenditure as an asset, the asset is carried at cost
 less any accumulated amortisation and accumulated
 impairment losses. Amortisation of the asset begins
 when development is complete, and the asset is
 available for use. It is amortised over the period of
 expected future benefit. Amortisation expense is
 recognised in the statement of profit and loss unless
 such expenditure forms part of carrying value of
 another asset. During the period of development, the
 asset is tested for impairment annually.
 The cost of inventories includes expenditure incurredin acquiring the inventories, production or conversion
 costs and other costs incurred in bringing them to their
 present location and condition.
 Net realisable value is the estimated selling price in theordinary course of business, less the estimated costs
 necessary to make the sale. The net realisable value of
 work-in-progress is determined with reference to the
 selling prices of related finished products.
 Raw materials 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 madeon an item-by-item basis.
 f. Retirement and other employee benefitsShort-term employee benefits Short-term employee benefit obligations are measuredon an undiscounted basis and are expensed as the
 related service is provided. A liability is recognised for
 the amount expected to be paid e.g., salaries and wages
 and bonus etc., if the Company has a present legal or
 constructive obligation to pay this amount as a result of
 past service provided by the employee, and the amount
 of obligation can be estimated reliably.
 Post-employment benefits
 Defined contribution plans
 A defined contribution plan is a post-employmentbenefit plan under which an entity pays specified
 contributions to a separate entity and will have no
 legal or constructive obligation to pay further amounts.
 The Company makes specified monthly contributions
 towards employee provident fund and employee state
 insurance scheme ('ESI') to Government administered
 scheme which is a defined contribution plan. The
 Company's contribution is recognised as an expense
 in the Statement of Profit and Loss during the period
 in which the employee renders the related service.
 Certain employees of the Company are also participants
 in the superannuation plan ("the Plan"), a defined
 contribution plan. The Company makes contributions to
 Life Insurance Corporation of India (LIC). Contribution
 made by the Company to the plan during the year is
 charged to Statement of Profit and Loss. The social
 security costs, paid for the overseas employees, are in
 the nature of defined contribution schemes as per the
 laws of that country.
 Defined benefit plansA defined benefit plan is a post-employment benefitplan other than a defined contribution plan. Gratuity
 is a defined benefit plan. The administration of
 the gratuity scheme has been entrusted to the Life
 Insurance Corporation of India ('LIC'). The Company's
 net obligation in respect of gratuity is calculated
 separately by estimating the amount of future benefit
 that employees have earned in the current and prior
 periods, discounting that amount and deducting the
 fair value of any plan assets.
 The calculation of defined benefit obligation isperformed annually by a qualified actuary using the
 projected unit credit method.
 Re-measurements of the net defined benefit liabilityi.e. Gratuity, which comprise actuarial gains and losses
 are recognised in Other Comprehensive Income (OCI).
 Remeasurements are not reclassified to profit or loss in
 subsequent periods. The Company determines the net
 interest expense (income) on the net defined benefit
 liability for the period by applying the discount rate
 used to measure the defined benefit obligation at the
 beginning of the annual period to the then- net defined
 benefit liability, taking into account any changes in the
 net defined benefit liability during the period as a result
 of contributions and benefit payments. Net interest
 expense and other expenses related to defined benefit
 plans are recognised in the Statement of Profit and
 Loss.
 When the benefits of a plan are changed or when a planis curtailed, the resulting change in benefit that relates
 to past service ('past service cost' or 'past service
 gain') or the gain or loss on curtailment is recognised
 immediately in the Statement of Profit and Loss. The
 Company recognises gains and losses on the settlement
 of a defined benefit plan when the settlement occurs.
 Compensated absencesThe Company's net obligation in respect of long-termemployee benefits other than post-employment
 benefits is the amount of future benefit that employees
 have earned in return for their service in the current and
 prior periods; that benefit is discounted to determine
 its present value, and the fair value of any related assets
 is deducted. Such obligation such as those related to
 compensate absences is measured on the basis of
 an annual independent actuarial valuation using the
 projected unit cost credit method. Remeasurements
 gains or losses are recognised in profit or loss in the
 period in which they arise. The Company presents the
 leave liability as a current liability in the balance sheet;to the extent it does not have an unconditional right to
 defer its settlement for 12 months after the reporting
 date. Where Company has the unconditional legal and
 contractual right to defer the settlement for a period
 beyond 12 months, the same is presented as non¬
 current liability.
