By a reference dated September 17	 1965	 the Government of West Bengal referred to the Sixth Industrial Tribunal the following question for adjudication: "Whether computation of bonus in respect of the accounting year ending 31st March 1965 payable to the employees is in accordance with the payment of Bonus Ordinance ? If not	 what should be the quantum of bonus for the employees ?" 754 The dispute between the appellant company and its employees arose in the following manner. The company 's accounting yearis from 1st April to 31st March of the following year and its books of account are maintained on the mercantile system of accounting. The company computed the amount of bonus payable to its employees under the Payment of Bonus Ordinance which was promulgated on May 29	 1965 and furnished on July 5	 1965 copies of its this computation to the three respondent Unions representing its employees. The available surplus and allocable surplus	 according to this computation	 were Rs. 49.96 lacs and Rs. 29.98 lacs respectively. On this basis the company declared the bonus at 13.28 per cent of the total wages paid to the employees. According to this computation	 the gross profits came to Rs. 2	70	61	234/ . Out of this the company deducted the following amounts allowed under the Ordinance	 namely: Rs. 28	64	000/ as depreciation admissible under the Income Tax Act	 1961; Rs. 9	00	000/ as development rebate. Rs. 1	36	33	000/ as direct taxes. Rs. 1	50	000/ as dividend on preference shares; Rs. 23	37	000/ as interest at 8.5 p.c. on paid up capital; Rs. 17	80	358/ as interest at 6 p.c. on reserves. Thus the available surplus came to Rs. 49	96	876/ 	 sixty per cent of which	 namely	 Rs. 29	98	125/ was the allocable surplus. The employees disputed the computation contending that the company had wrongly reduced the gross profits and the available surplus and that the following amounts should be added back	 viz. 	provision for gratuity Rs. 18	38	605/ and provision for doubtful debts Rs. 50	000/ . They also challenged deduction of interest on the reserves on the ground that the capital reserve of Rs. 57	00	151/ was artificially arrived at by a mere revaluation of the company 's fixed assets as on April 1	 1956. They also disputed the figures of depreciation	 development rebate and direct taxes deducted by the company while working out the available surplus. Parliament in the meantime passed the which by sec. 40 repealed the Ordinance but which saved all things done and action taken under the 'Ordinance as having been done or taken under the Act. On September 27	 1965 company paid	 subject to the result of the reference	 bonus at the rate of 13.28 percent of the wages including dearness allowance to its employees. In its award the Tribunal allowed Rs. 23	48	226/ instead of Rs. 28	82	261/ claimed by the company as depreciation. Simiearly it allowed only Rs. 7 lacs instead of Rs. 8	87	371/ claimed 755 by the company as development rebate. As regards Rs. 18.38 lacs claimed under the head of gratuity	 the Tribunal held that amount was not a reserve but a provision and	 therefore	 was not liable to be added 'back. But it held that the company could deduct only Rs. 10 lacs and odd as also Rs. 1.31 lacs and Rs. 87	000/ and odd actually paid during the year to employees who retired during that year and added back the balance of Rs. 6 lacs to the gross profits. Except for these amounts	 the TribUnal accepted the rest of the company 's computation. In the result the Tribunal found the available surplus and the allocable surplus to be 54 lakhs and odd and Rs. 32.42 lacs respectively and directed payment of bonus at 14.55 per cent of the total wages. Both the Unions and the company obtained special leave and filed appeals challenging the correctness of the Award. In the profit and loss account for the year 1964 65	 the Company had shown Rs. 17 chores and odd as gross receipts and out of that amount had deducted diverse amounts as expenditure including the sum of Rs. 23	48	226/ by way of depreciation. In its computation filed before the Tribunal	 the Company	 however	 claimed depreciation at Rs. 28.82 lacs worked out by its auditors in accordance with the provisions of the Income Tax Act	 1961. The Unions disputed this amount on the ground (1 ) that there was no evidence that the amount of depreciation came to Rs. 28.82 lacs and (2) that since the profit and loss account mentioned Rs. 23.48 lacs as depreciation	 the company could claim that amount only. The Tribunal accepted the Unions ' contention stating that there was nothing to show that the company through mistake had shown Rs. 23.48 lacs as depreciation in the profit and loss account and that subsequently on finding out the mistake it had revised in its computation depreciation at Rs. 28.82 lacs. The Tribunal	 as we shall presently show	 was in error in confusing depreciation claimed by it as a deduction under sec. 6 of the Act and in thinking that the company had made or claimed to have made a mistake and was trying to correct such mistake. Under sec. 205( 1 ) of the 	 no dividend can be declared or paid by a company for any financial year except out of profits arrived at after providing for depreciation in accordance with sub sec. Sub sec. (2) provides different methods of calculating depreciation	 one of which is to calculate it by dividing 95 per cent of the original cost of each of the depreciable asset by a specified period in respect of each such asset. The depreciation deducted in the expenditure column in the P&L account therefore was the depreciation worked out under sec. 205 ( 2 ) of the Companies 'Act. Under sec. 2 ( 18 ) of the Bonus Act	 gross profits mean gross profits calculated under sec. In the case of companies other than a banking company	 gross profits under Sec. 4 are to be computed in the manner laid 756 down in the 2nd Schedule. That Schedule requires adding back to the net profit shown in the P & L account of depreciation deducted in that account while computing gross profits. Obviously	 the depreciation so to be added back is the one worked out by the company under sec. 205 (2 ) of the . Section 6 of the Bonus Act provides that having arrived at the gross profits under sec. 4 read with the 2nd Schedule	 the Company is entitled to deduct therefrom depreciation admissible under sec. 32( 1 ) of the Income Tax Act	 that is	 such percentage on the written down value as may	 in the case of each of the classes of assets	 be prescribed. The fact that the company while preparing its P & L Account and its computation (exhibit 6) produced before the Tribunal	 had kept the distinction between depreciation worked out under the and the one to be worked out under the Income tax Act for the purposes of the Bonus Act is clear from the evidence of its witness	 Verma. It was for this reason that Rs. 23 lacs and odd were shown as depreciation in the P & L Account while in the computation (exhibit 6) the company claimed Rs. 28.64 lacs as depreciation. There was	 therefore	 no question of the company having made any mistake in calculating depreciation in the P & L Account or its trying to amend that mistake as erroneously thought by the Tribunal. The only mistake	 the company claimed it had made	 was that the true figure of depreciation deductible under sec. 6(a) of the Bonus Act was Rs. 28.82 lacs and not Rs. 28.64 lacs. The Company produced a certificate of its auditors (exhibit U 2) dated December 20	 1965 wherein the auditors certified that on the records produced before them the true figure of depreciation would be the revised figure of Rs. 28.82 lacs and not Rs. 28.64 lacs. But the controversy between the parties was not confined to the difference between these two figures. There were three figures for depreciation before the Tribunal	 Rs. 23 lacs and odd shown in the P & L Account	 Rs. 28.64 lacs shown in the computation and Rs. 28.82 lacs subsequently claimed by the company as the revised figure of depreciation. The last two figures were taken by the company from its auditors ' certificate certifying first Rs. 28.64 lacs and	 latex on	 revising that figure to Rs. 28.82 lacs on certain further records and information produced before them. The evidence of Verma shows clearly that the Unions disputed the Company 's calculations of depreciation. When questioned by them	 Verma could only say that the calculations were done not by him but by the Secretarial Department and	 therefore	 was not in a position to answer questions in that regard. No witness from the Secretarial Department was produced. As regards their books and records produced before the auditors	 his only answer was: 757 "So far as books and records mentioned in the first part of Ext. U 2 are concerned	 the books and record relating to the branches were produced before the representatives of the	 auditors ' firm there	 and the other books and records were produced there before the auditors ' firm. So far as the record mentioned in the second part of the certificate are concerned	 they are different records. The informations and explanations given to the auditors were given verbally after consulting our books of accounts". These books and records not having been produced or disclosed	 there was obviously no opportunity to the Unions to verify either of the two figures	 viz.	 Rs. 28.64 lacs or Rs. 28.82 lacs. It is true that Verma said that the calculations shown to the auditors could be produced but he qualified the offer by saying that would be done if the Tribunal required. Since the company claimed the deduction of depreciation	 it stands to reason that the burden of proof that the depreciation claimed by it was the correct amount in accordance with the Income Tax Act was on the Company and that burden the company must discharge once its figures were challenged. But it was; contended that once the company produced its auditors ' certificate. that should be sufficient and must be accepted and that the Tribunal should not insist either on the auditors proving their certificate or on the company proving depreciation on each and every item of depreciable asset. Such an enquiry before the Tribunal	 it was argued	 would be a harassing and prolonged enquiry	 not contemplated in industrial adjudication and	 therefore	 the Tribunal ought to have accepted as correct Rs. 28.82 lacs certified by the auditors. Under sec. 23 of the Act the presumption of accuracy is allowed only to the balance sheet and the P & L Account of companies. No such presumption is provided for by the Act to auditors ' certificates. Speaking of rehabilitation amount deductible as a prior charge under the Full Bench formula while working out the available surplus this Court in Khandesh Spg. ana Wvg. Mills Co. Ltd. vs Rashtriya Girni Kamgar Sangh(1) observed at page 847 as follows: "The importance of this question (the procedure to be followed for ascertaining facts) in the context of fixing the amount required for rehabilitation cannot be over estimated. The item of rehabilitation is generally a major item that enters. into the calculations for the purpose of ascertaining the surplus and	 therefore	 the amount of bonus. So	 there would be a tendency on the part of the employer to inflate this figure and the (1) ; 	847. C. 1./69 2 758 employees to deflate it. The accounts of a company are prepared by the management. The balance sheet and the profit and loss account are also prepared by the company 's officers. The labour have no concern in it. When so much depends on this item	 the principles of equity and justice demand that an Industrial Court should insist upon a clear proof of the same and also give a real and adequate opportunity to the labour to canvass the correctness of the particulars furnished by the employer. " The necessity of proper proof of the correctness of statements in the balance sheet was repeated in Petlad Turkey Red Dye Works Ltd. vs Dyes & Chemical Workers ' Union(1). These observations made with regard to balance sheets and P & L accounts would equally apply to statements made in 	the auditors ' certificates 'prepared on the instructions and information supplied to them by employers. Mere production of auditors ' certificate	 especially when it is not admitted by labour	 not by the auditors but by the employees of the company who admitted not to have been concerned with its preparation or the calculations on which it was based. would not be conclusive. We do not say that in such a case the Tribunal should insist upon proof of depreciation on each and every item of the assets. It should	 however	 insist on some reasonable proof of the correctness of the figure of depreciation claimed by the employer either by examining the auditors who calculated and certified it or by some other proper proof. Depreciation in some cases would be of a large amount affecting materially the available surplus. Fairness	 therefore	 requires that an opportunity must be given 'to the employees to verify such figures by cross examination of the employer or his witnesses who have calculated depreciation amount. Notwithstanding the Unions ' challenge to the figure of depreciation claimed by the company	 the only thing that the company did was to examine Verma	 who admittedly had nothing to do with its calculation	 and to produce through him the said certificate. In our view	 that was neither proper nor sufficient. The proper course for the Tribunal in such a case was to insist upon the company adducing legal evidence in support of its claim instead of taking the figure of depreciation from the P & L account which was not worked out in accordance with the Income Tax Act but under sec. 205 of the 	 and saying that the Company had failed to prove that it was a mistaken figure. In our view	 the question as to the correct amount of depreciation must go back to the Tribunal for a fresh decision. The Tribunal should give opportunity to the Company to prove its claim for depreciation by reasonable proof and to the Unions to test such evidence by cross examination or otherwise. (1) ; 	 909. 759 An error of the same type seems to have been committed by the Tribunal in the matter of development rebate. It allowed Rs. 7 lacs as development rebate. instead of Rs. 8.87 lacs. claimed by the Company. Under sec. 33 of the Income Tax Act	 an assessee is allowed by way of development rebate a certain percentage of the cost of machinery or plant depending on the date of its installation. Section 34(3) of that Act provides	 however	 that the said allowance shall not be given unless an amount equal to 75 per cent of the development rebate to be allowed is debited to the P & L account of the relevant previous year and credited to a reserve account to be utilised by the assessee in the 8 years next following for the purposes of the undertaking. Accordingly	 the Company appropriated Rs. 7 lacs to the development rebate reserve as it was bound to do if it wanted to claim development rebate. The Company took the round figure Rs. 9 lacs instead of Rs. 8.87 lacs for development rebate and credited Rs. 7 lacs	 being 75 per cent thereof to the development rebate reserve. Under the Second Schedule to the Bonus Act	 read with sec. 4 thereof the Company is required while computing its gross profit to add the development rebate and as footnote 1 in that Schedule shows "to the extent charged to profit and loss account"	 that is	 Rs. 7 lacs. Under sec. 6(b) of the Bonus Act	 the Company is entitled	 however	 to deduct out of the gross profits arrived at under sec. 4	 the whole of the development rebate admissible under the Income Tax Act	 i.e.	 the amount	 75 per cent of which comes to Rs. 7 lacs. The error which the Tribunal fell into was in mixing up the development rebate reserve to which the Company had to appropriate Rs. 7 lacs in P & L account and the development rebate of Rs. 8.87 lacs allowable to it under sec. 6 of the Act. Mr. Chari for the Unions fairly conceded that he could not challenge this position. There was	 therfore	 no justification for the Tribunal to allow Rs. 7 lacs only instead of Rs. 8.87 lacs as development rebate. The next question relates to a sum of Rs. 18.38 lacs	 being the estimated liability under two gratuity schemes framed by the Company	 which was deducted from the gross receipts in the P & L account. In 1960 the Company introduced a gratuity scheme for its employees other than its officers. Under that scheme gratuity was payable on the termination of an employees 's service either due to retirement	 death or termination of service	 the amount of gratuity payable being dependent on his wages at that time and the number of years of service put in by him. The Company had worked out on an actuarial valuation its estimated liability and made provision for such liability not all at once but spread over a number of years. Thus in 1959 60	 1960 61 and 1961 62 the Company allocated towards this liability Rs. 5 lacs. Rs. 10 lacs and Rs. 5 lacs respectively from out of the profits	 760 debiting these amounts in the profits and loss account. In all Rs. 40 lacs have so far been provided in the aforesaid manner against the said liability. The practice followed by the Company is that every year the Company works out the additional liability incurred by it on the employees putting in every additional year of service. Whenever an employee retires	 the amount of gratuity payable to him is debited against the amount provided for as aforesaid. The amount so paid is not debited in the P & L account as an outgoing or expenditure but against the estimated liability provided as aforesaid. In 1964 65 the	 Company introduced a similar gratuity scheme for its officers. According to the Company	 the estimated liability under this scheme was worked out at Rs. 20 lacs. But instead of providing the whole for it provided only Rs. 11.31 lacs. It also provided Rs. 7 lacs under the scheme for its non officers against the liability for service put in by them in that year. Out of Rs. 18.38 lacs so provided	 the Company paid as gratuity Rs. 1	31	585/ and Rs. 87	295/to officers and other employees who retired during 1964 65	 debiting as aforesaid	 these amounts not as an outgoing or expenditure but against the said amounts of Rs. 11 lacs and Rs. 7 lacs. The Company claimed that it was entitled to. deduct the balance of Rs. 16 lacs from the gross receipts in the P & L account while working out its net profit. The Unions contended that the Company could deduct from the gross receipts only Rs. 1.31 lacs and Rs. 87	000/ and odd actually paid during the year. The Company	 on the other hand	 maintained that what it had 'done was legitimate and was warranted by the principles of accountancy and	 therefore	 the whole amount of Rs. 18.38 lacs was deductible in arriving at its net profits. What the Tribunal did	 however	 was that instead of squarely facing this controversy	 it held that as the Company had in the former years debited Rs. 5 lacs e.g.	 in 1959 60 and 1961 62	 it would allow only Rs. 5 lacs for each of the two schemes. Thus it allowed Rs. 10 lacs as dubitable in the P & L account in addition to the said Rs. 1.31 lacs and Rs. 87	000/ and disallowing the balance of Rs. 6 lacs added back that amount in the net profits shown in the P & L account. The contention of Mr. Chari was two fold: (1 ) that the amount which could be debited was that which was actually paid and the Company was not entitled to debit in the P & L account any amount worked out by it as estimated liability. The Tribunal. therefore	 was not justified in allowing the Company to debit any such amount and that the Tribunal arbitrarily fixed Rs. 10 lacs and allowed wrongly that amount to be deducted; and (2) even if such estimated liability was debitable	 the appropriation amounted to a reserve and under the Bonus Act such a reserve had to be 761 added back while working out the gross profits under the 2nd Schedule to the Act. Two questions	 therefore	 arise: (1) whether it is legitimate in such a scheme of gratuity to estimate the liability on an actuarial valuation and deduct such estimated liability in the P & L account while working out its net profits; and (2).i.f it is	 whether such appropriation amounts to a reserve or a provision. If it is a reserve	 obviously the amount has to be added back while computing the gross profits. But in that event the Company would be entitled to interest thereon at 6 per cent per annum under Item 1 (iii) of the Third Schedule to the Act. In the case of an assessee maintaining his accounts on mercantile system	 a liability already accrued	 though to 'be discharged at a future date	 would be a proper deduction while working out the profits and gains of his business	 regard being had to the accepted principles of commercial practice and accountancy. It is not as if such deduction is permissible only in case of amounts actually expended or paid. Just as receipts	 though not actual receipts but accrued due or brought in for income tax assessment	 so also liabilities accrued due would be taken into account while working out the profits and gains of the business. A Company carrying on business of buying land and selling it after development sold certain plots	 received a part of the price but entered the whole of the price receivable as it maintained its books of accounts on mercantile method. It also debited a certain sum	 being the estimated expenditure for the developments it undertook to carry out within six months from the execution of the sale deeds although no part of such expenditure was actually incurred during that year. It was held that having regard to the accepted commercial practice and trading principles and there 'being no prohibition against it in the Income Tax Act	 deduction of such estimated liability even though it did not come under any specific provisions of sec. 10(2) of the Income Tax Act	 1922 was permissible; (see Calcutta Company Ltd. vs CJ.T.(1) Such a deduction of an accrued liability though not actually paid is not confined to the Income Tax Act only but is also perrnissible under the Wealth Tax Act	 1957. In Commissioner of Wealth Tax vs Standard Vacuum Oil Co. Ltd.( 2) demands in respect of payment of tax under sec. 18A of the Income Tax Act	 1922 were made against the 'assessee company for 1956 57. The final installment of Rs. 47 lacs and odd for each of the two years was outstanding on the respective valuation dates. The question was whether the demand 	for such tax could be deducted while determining the net wealth of the Company. This Court held that a debt is "owed ' when an order is passed under sec. 18A and a notice of demand is sent. The amount mentioned in the notice begins to be 'owed ' till a new figure is (1) [1960]1 S.C.R. 185. (2) ; 762 substituted by the assessee under sec. 18A(2) of the Income Tax Act. But till that is done	 the amount is ascertained and there is a statutory liability to pay the amounts mentioned in the order under sec. 18A(1) and were debts on the valuation dates and	 therefore	 deductible for the purpose of arriving 'at the Company 's net wealth. The Court also held that a condition subsequent	 the fulfilment of which may result in the reduction or even extinction of the liability	 would not have the effect of converting that liability into a contingent liability. The decision	 no doubt	 turned on the meaning of 'debt ' as defined by sec. 2(m) of the Wealth Tax Act	 the. Court there holding that the statutory liability to pay the amount mentioned in the order commenced when the demand notice was served and	 therefore	 the liability did exist in present. In Kesoram Industries and Cotton Mills Ltd. vs C.W.T.(1) also a case under the Wealth Tax Act	 the appellant company showed in its P & L account two amounts: (1 ) the amount of dividend proposed to be distributed for that year and (2) another sum as a provision for tax liability under the income Tax Act	 1922. The question was whether these two sums were debts and could be deducted while computing the Company 's net wealth. It was held that the dividend amount was not a debt as on the valuation date nothing more than a recommendation by the Directors had taken place. But as regards the estimated tax liability	 it was held that it was a debt inasmuch as the liability to pay the tax was in present though payable in future and was in respect of an ascertainable sum of money. In Standard Mills Co. Ltd. vs Commissioner of Income Tax(2) the decision turned on the question whether an estimated liability under gratuity schemes framed under Industrial awards amounted t0 debts and could be deducted while computing the net wealth. On reliance having been placed on Southern Railway of Peru Ltd. vs Owen(a) a decision to which we shall presently come the Court observed ' at page 773 that decision had no relevance to the question before it as the House of Lords in that decision was concerned in determining the deductibility of the present value of a liability which may arise in future in the computation of taxable income for the relevant year under the Income Tax laws The Court held	 in view of the terms of sec. 2(m) of the Wealth Tax Act	 that as the liability to pay gratuity was not in presents but would arise in future on the termination of service i.e. on retirement	 death or termination; the estimated liability under the schemes would not be a debt and	 therefore	 could not be deducted while computing the net wealth. These observations show that the Court was of the view that though such a liability is a contingent liability and therefore not a 'debt ' under sec. 2(m) of the Wealth Tax Act	 it would be deductible under the Income Tax Act while (1) ; (2) ; (3) ; 763 computing the taxable profits. In the instant case	 the question is not whether such estimated liability arising under the gratuity schemes amounts to a debt or not. The question that concerns us is whether while working out the net profits a trader can provide from his gross receipts his liability to pay a certain sum for every additional year of service which he receives from his employees. This	 in our view	 he can do	 if such liability is properly ascertainable and it is possible to arrive at a proper discounted present value. Even if the liability is a contingent liability	 provided its discounted present value is ascertainable	 it can be taken into account. Contingent liabilities discounted and valued as necessary can be taken into account as trading expenses if they are sufficiently certain to be capable of valuation and if profits cannot be properly estimated without taking them into account. Contingent rights	 if capable of valuation	 can similarly be taken into account as trading receipts where it is necessary to do so in order to ascertain the true profits: (see C.N. Beatti 's Elements the Law of Income and Capital Gains Taxation 8th ed. 54). In Southern Railway of Peru Ltd. vs Owen(1)	 the House of Lords was concerned with the problem similar to. the one before us and	 therefore	 the observations made there would be of assistance. An English Company operating a railway in Peru was under the laws of that country liable to pay its. employees compensation on the termination ' of their services either by dismissal or on termination of service by notice or on such termination by death or affluence of contractual time. The compensation so paid was an amount equivalent to one month 's salary at the rate in force at the date of determination of every year of service. The Company claimed to be entitled to charge against each years receipts the cost of making provision for the retirement payments which would ultimately be thrown on it	 calculating the sum required to be paid to each employee if he retired without feature at the close of the year and setting ' aside the aggregate of what was required insofar as the year had contributed to the aggregate. The House of Lords rejected the deductions on the ground that in calculating the deduction the company had ignored the factor of discount. But their Lordships recognised the principle that the company was entitled to charge against each year 's receipts the cost of making provision for the retirement payments which would ultimately be payable as the company had the benefit of the employees ' services during the year provided the present value of the future payments could be fairly estimated. The contention on behalf of the Crown was very nearly the same as the one before us. Counsel conceded	 that a trader computing his taxable profits for a particular year may properly deduct not only the payments actually made to his employees but (1) ; 764 also the present value of any payments in respect of their services in that year to be made in a subsequent year if it can be satisfactorily estimated. But it was argued that proposition would not apply to that case as the company was not in any year under a definite obligation to pay its employees lump sums on the termination of their employment as in each case the right to a lump sum was contingent on certain conditions being fulfilled and ' so the prospective liability remained contingent until the service was actually ended. The lump sum could not be regarded as earned or payable in respect of a particular year of service and	 therefore	 the whole sum should be debited in the account of the last year of service. This contention was not upheld. In the course of his opinion	 Lord Radcliffe cited with approval the dictum of Lord Haldane in Sun Insurance Office vs Clark(1) at p. 455	 namely: "It is plain that the question of what 	is or is not profit or gain must primarily be one of fact	 and of fact to be ascertained by the tests applied in ordinary business. Questions of law can only arise when (as was not the case here) some express statutory direction applies and excludes ordinary commercial practice	 or where	 by reason of its being impracticable to ascertain the facts sufficiently	 some presumption has to be invoked to fill the gap. " Holding that there was no such statutory rule prohibiting the commercial practice of providing for such an estimated liability for each year	 he compared the: two systems and observed at pp. 351 352 as follows: "Now the question is how ought the effects of this statutory scheme to be reflected in the appellant 's accounts of the annual profits arising from its trade ? One way	 which is certainly the simplest one	 is to let the payments made fall entirely as expenses of the year of payment and ignore any question of making provision for the maturing obligation during the years of service that precede it . . It has one considerable advantage; no element of estimate or valuation appears in the profit assessment and nothing is charged to profits except the actual cash outgoing. But	 when this has been conceded	 I think that there is the very serious disadvantage to be set against the inefficient method of arriving at the true profits of any one year. The retirement benefit is not obviously paid to obtain the services given in the year of retirement. The incident of retirement payments must be variable from year to year	 and (1) ; 765 they may inordinately depress the profits of one year just as they may inordinately inflate the profits of another. It is true that the company carries on business from one year to another	 but it is not charged on the average of its annual profits. Tax rates and allowances themselves vary and	 apart from that	 to charge tax on a profit unduly accelerated or unduly deferred is	 in my opinion	 no more respectable an achievement than to admit that the annual accounts of business do in some cases require the introduction of estimates or valuations if a true statement of profit i	s to be secured. Another method is that which the appellant is seeking to establish with regard to its assessments for the four years 1947 1950 . . What the appellant claims the right to do is to charge against each year 's receipts the cost of making provision for the retirement payments that will ultimately be thrown upon it by virtue of the fact that it has had the benefit of its employees ' services during that year. As a corollary it will not make any charge to cover the actual payments made in the year in respect of retirement benefits. Only by such a method	 it is said	 can it bring against the receipts of the year the true cost of the services that it has used to earn those receipts. Generally speaking	 this must	 I think	 be true. For	 whereas it is possible that any one of its many employees may forfeit his benefits and so never require a payment	 the substantial facts of the situation are that when the company has paid every salary and wage 'that is due for current remuneration of the year it has not by any means wholly discharged itself of the pecuniary burden which fails upon it in respect of the year 's employment. " Agreeing with the company 's claim he observed that provision for retirement payments would give an accurate reflection of the true costs of earning the year 's receipts than merely charging against them the year 's payment to employees who retired in the year. That there is no rule against providing for any such contingent liability but on the contrary such a provision is permissible can be seen from the form of balance sheet in Schedule VI to the where provisions for taxation	 dividends. provident fund schemes	 staff benefit schemes and other items for which a company is contingently liable are to be treated as current liabilities and	 therefore	 dubitable against the gross receipts. Schedule VI	 	 lays down the requirements of profit and loss account and el. 3 (ix) of it provides that a profit and loss account shall set out amongst other things the aggregate of amounts set aside or provisions made for meeting. specific liabili 766 ties	 contingencies or commitments. But the contention was that though Schedule VI to the may permit a provision for contingent liabilities	 the Income tax Act	 1961 does not	 for under sec. 36(v) the only deduction from profits and gains permissible is of a sum paid by an assessee as an employer by way of his contribution towards an ' approved gratuity fund created by him for the exclusive benefits of his employees under an irrevocable trust This argument is plainly incorrect because sec. 36 deals with expenditure deductible from out of the taxable income already assessed and not with deductions which are to be made while making the P & L account. In our view	 an estimated liability under gratuity schemes such as the ones before us	 even if it amounts to a contingent liability and is not a debt under the Wealth Tax Act if properly ascertainable and its present value is fairly discounted is deductible from the gross receipts while preparing the P & L account. It is recognised in trading circles and we find no rule or direction in the Bonus Act which prohibits such a practice. The next question is whether the amount so provided is a provision or a reserve. The distinction between a provision and a reserve is in commercial accountancy fairly well known. Provisions made against anticipated losses and contingencies are charges against profits and	 therefore	 to be taken into account against gross receipts in the P & L account and the balance sheet. On the other hand	 reserves are appropriations of profits	 the assets by which they are represented being retained to form part of the capital employed in the business. Provisions are usually shown in the balance sheet by way of deductions from the assets in respect of which they are made whereas general reserves and reserve funds are shown as part of the proprietor 's interest: (See Spicer and Peglar 's Book keeping and Accounts	 15th ed. p. 42). An amount set aside out of profit and other surpluses	 not designed to meet a liability contingency commitment or diminution in value of assets known to exist at the date of the balance sheet is a reserve but an amount set aside out of profits and other surpluses to provide for any known liability of which the amount cannot be determined with substantial accuracy is a provision	 (see William Pickles Accountancy	 Second Edn.	 192	 Part III	 cl. 7	 Sch. VI to the which defines provision and reserve). Under sec. 23 of the Bonus Act	 there is 'a presumption of the genuineness of the P & L account produced by the company unless it is challenged in the manner provided therein. The Company 's case was that the estimated liability under the gratuity schemes in respect of the accounting year was ascertainable with fair accuracy under the actuarial valuation and Rs. 16 lacs which it took into account while making it P & L account was the 767 present discounted liability. This position does not seem to have been disputed before the Tribunal. The principal contention urged against that figure was not that the estimated liability was not ascertainable or as in the case of Southern Railway of Peru(1) that it did not represent the present discounted value	 but that the Bonus Act permits only the deduction of the amount actually paid during the accounting year. This was also the principal contention of Mr. Chari before us. Mr. Ramamurthi	 appearing for one of the interveners	 argued that though it may be possible to take into account such a contingent liability in arriving at the true profits and gains under the Income tax Act	 it would not be so under the Bonus Act as the scheme of the Act treats the accounting year as a unit and	 therefore	 reserves or provisions on the footing of estimated liabilities to be paid in future cannot be taken into account. But under the Income tax Act also the previous year is a unit and it is only the profits and gains during that year which are taxable. If under the Income tax Act an estimated liability ascertainable with substantial accuracy can be taken into account for arriving at the true profits and gains	 there is no reason why the same cannot be done under the Bonus Act unless 'there is any provision therein forbidding such a practice recognised by commercial accountancy. No such provision was shown to exist in the Bonus Act. The Tribunal in allowing Rs. 10 lacs out of the estimated 'Rs. 16 lacs impliedly accepted the principle canvassed by the company. It	 however	 allowed only Rs. 10 lacs because it thought it to be excessive as in some prior years the Company had deducted Rs. 5 lacs. But this was not done on the ground that the estimate of Rs. 16 Iacs was not warranted on any valuation. In our view	 in the absence of any challenge as to the correctness of the valuation and in the absence of any challenge that such liability cannot be estimated on any fair standard	 the Tribunal ought to have allowed the whole of Rs. 16 lacs to be deducted while arriving at the net profits in the P & L account. Turning now to the appeal filed by the employees two question besides those already disposed of were raised: one dealing with interest on capital reserve and the other relating to the amount of direct taxes to be deducted from the gross profits. As regards the first question	 Verma 's evidence was that the Company had revalued its fixed assets in 1956.and credited the difference of Rs. 57 lacs between its cost and the value fixed on such revaluation	 to the capital reserve. The Tribunal accepted the valuation as bona fide and allowed interest on the said reserve at 6 per cent in accordance with sec. 6(d) and el. 1 (iii) of the 3rd Schedule. Mr. Chari 's contention was that the revaluation (1) ; 768 by the director in 1956 was fictitious; that the difference of Rs. 57 lacs was a mere book adjustment and did not add to the wealth of the Company and though that amount was transferred to the capital reserve it was not as if any additional amount became available for the Company 's business and therefore	 no interest was permissible on such an artificial amount. At first blush it would seem as if there is some force in this contention	 for it would be possible for a company to deflate its gross profits by fictitiously revaluing its fixed assets at regular intervals red claiming interest on the excess by carrying such excess to capital reserve and to reduce thus labor 's claim to bonus. In the present case the revaluation was made as early as in 1956 and it does not appear that it was ever objected to either by 'the Company 's auditors or by any one else concerned with the Company 's management. It cannot	 therefore	 be legitimately said that it was done for any oblique purpose	 much less with a view to defeat the labor 's claim to bonus. It is true that such revaluation does not bring in any tangible additional amount into the company 's coffers which it can use for its business. But under sec. 211 of the every balance sheet of a company must give a true and fair view of the state of affairs of the company as at the end of the financial year. VI to the also provides that where sums have been written off on a reduction of capital or a revaluation of assets the balance sheet subsequent to such reduction or revaluation must show the reduced or the increased figures as the case may be. Apart from the provisions of the 	 it is a recognised principle of accountancy to transfer the increased value of assets on revaluation to a capital reserve account. Such an increased figure is an unrrealised accretion in the value of a fixed asset. (see Pickles Accountancy 2nd Edn. 103 and 935). So that the fact such an increased figure does not actually bring in any additional amount to the Company does not make the capital reserve any the less a reserve. Nor is it possible to postulate that if such a claim is allowed to be deducted	 the management would go on artificially inflating the value of the fixed assets with a view 'to claim interest. In the first place	 if such an inflation is made mala fide	 the Tribunal can always reject it. In the second place	 it is hardly profitable for a company to resort to such a practice for under the Wealth Tax Act the company would be liable to an increased assessment. Section 7(2) of that Act provides that where an assessee is carrying on a business for which accounts are maintained regularly	 the Wealth Tax Officer may instead of determining separate the value of each asset held by the assessee determine the net value of the asset of the business as a whole having regard to the balance sheet of such business as on the valuation date. In Kesoram Industries vs Commissioner of Wealth Tax(1) the assessee sought (1) ; 769 to argue exactly what Mr. Chari contended	 namely	 that the revaluation of the assets made by him did not represent the true value of the assets. That contention was rejected and this Court held that the Wealth Tax Officer was entitled to rely on such revaluation and proceed to assess on the basis of the net wealth shown as a result of such revaluation. We do not	 therefore	 see any justification for the apprehension felt by Mr. Chaff	 for	 by trying to reduce the gross profits	 the Company would land itself into being assessed on a higher net wealth. The Tribunal was	 in our view	 right in accepting the figure of Rs. 57 lacs and deducting interest thereon from the gross profits. There remains now the question regarding computation of direct taxes. Section 6(c) of the Act provides: "subject to the provisions of section 7	 any direct tax which the employer is liable to pay for the accounting year in respect of his income	 profits and gains during that year;" Section 7 inter alia provides: "For the purpose of clause (c) of section 6	 any direct tax payable by the employer for any accounting year shall	 subject to the following provisions. be calculated at the rates applicable to the income of the employer for that year	 . . The Company claim a deduction from the gross profits of Rs	 145 lacs as direct taxes. It had made provision	 however; for Rs. 130 lacs for direct taxes in the P & L account. In its computation it had made a provision for Rs. 136 Iacs. At the stage of the evidence and arguments it contended however that the proper amount would be Rs. 145 lacs. It claimed that direct taxes are to be worked out under sec. 6(c) on the gross profits worked out under sec. 4 less the prior charges allowable under sec	 6	 namely	 depreciation and development rebate	 but without deducting from such balance the bonus payable by the Company in the particular accounting year. The Tribunal accepted the contention and allowed Rs. 145 lacs. as direct taxes to be deducted under section 6 (c). This conclusion has been seriously disputed by the Unions. Mr. Chari 's argument was that the Act lays down its own statutory formula for working out available surplus and allocable surplus	 that the deduction from gross profits allowable are those permissible under the Act	 namely	 depreciation admissible in accordance with the provisions ' of sec. 32(1) of the Income tax Act	 the development rebate and subject to the provisions of sec. 7 of the Act	 the amount of direct taxes which the employer "is liable to pay" for the accounting year in respect of "his income	 profits and gains during that year". Mr. Chari laid stress on the 770 words "is liable to pay" ' and "in respect of his income	 gains and profits during that year" and argued that inasmuch as cl. (c) incorporates 'the language of the Income tax Act	 it contemplates that the employer is entitled to deduct his actual tax liability. Such liability	 therefore	 is to be worked out in accordance with the provisions of the Income tax Act and other relevant Acts by first arriving at the actual taxable income	 gains and profits under those Acts and then computing the taxes at rates provided by them for that particular accounting year. He argued that since cl. (c) is subject to the provisions of section 7	 the only departure permissible under the Act is that which is provided in section 7. His contention thus was that the Tribunal must start its calculations from the net profit shown in the P & L account which would have made provision for direct taxes and then deduct from the gross profits calculated under section 4 the prior charges permissible under section 6. The provision for direct taxes made in the P & L account would be computed after deducting from the gross receipts such deductions	 allowances	 reliefs	 rebates	 credits etc. as are permissible under the Income tax Act which would include the bonus amount payable during the year	 for	 without such deduction the P & L account cannot reflect the true net profit of the employer. The Company 's contention	 on the other hand	 was that the employer is entitled to compute his tax liability without deducting first the amount of bonus he would be liable to pay from out of the amount computed under section 4 and section 6. Mr. Palkhiwala submitted from the different provisions of the Act that the concept of actual tax liability under the Income tax Act is foreign to the Bonus Act inasmuch as the Bonus Act is concerned with gross profits calculated in accordance with section 4 and Sch. II	 and that section 7 to which section 6(c) is made subject	 militates against the concept of actual tax liability as worked out under the Income tax Act. The contention was that prior to the enactment of the Act when available surplus was worked out under the Full Bench Formula bonus was not deducted while arriving at. the amount of income tax deductible from gross profits	 that Parliament could not possibly have contemplated a departure from the course followed in a number of decisions both of courts and tribunals and suddenly decided to incorporate into this Act the complicated and elaborate provisions of the Income tax Act and throw the burden on Industrial Tribunals to work out deductions	 allowances	 reliefs	 rebates etc. under the Income tax Act and then finally to assess the actual tax liability. It was submitted that what has to be done by the Tribunal is first to work out gross profits under section 4 and Sch. II and then to deduct therefrom the prior charges under section 6 (a ) and (b) and estimate direct taxes on the balance and thus arrive at the available surplus. The controversy thus is one of principle rather than on the amount deducted by the Tribunal by way of direct taxes. 771 Before we attempt to resolve this controversy	 it will be worth our while to recount the principle consistently follow before the passing of this Act	 not with a view to interpret section 6(c)	 but to ascertain whether Parliament has made a departure from that principle and laid down a new procedure on which direct taxes are to be computed. Mr. Chari 's contention was that the Bonus Act is drafted on a clean slate giving a go bye to the earlier principle of working out bonus	 and	 therefore	 we must proceed on the footing of the language used in section 6(c). At first sight it would appear that the language of el. (c) lends support to his contention. But acceptance of that contention would mean incorporating into the Bonus Act the elaborate and complicated provisions of not only the Income tax Act but other Acts levying direct taxes and throwing a considerable burden on Tribunals	 least equipped with working out the provisions of those Acts entailing inevitably prolonged enquiries. Therefore	 we must proceed cautiously in examining the scheme of. the Act before we conclude on the interpretation to be given to section 6(c) and section 7. Calculating the avail. able surplus under the Full Bench Formula used to work out nationally the amount of bonus which they thought would be awarded and deducted that amount from the gross profits	 on the remaining balance of which	 income tax payable by the employer would be determined. The result of this procedure was that the amount of tax so worked out was proportionately less. Deprecating this procedure	 Gajendragadkar	 J.	 (as he then was) observed in Associated Cement Companies Ltd. vs The Workmen(1) as follows: "Logically it is only after all the prior charges have been determined and deducted from the gross profits that available surplus can be ascertained; and it is only after the available surplus is ascertained that the question of awarding bonus can be considered. Some tribunals seem 'to work out nationally the amount of bonus which they think can be awarded and placed that amount higher up in the process of making	 calculations before the income tax payable is determined . We wish the make it clear that this procedure should not be followed." In Crompton Parkinson (Works) Private Ltd. vs Its Workmen(2) disapproval of the said procedure was once again voiced	 Das	 C.J. observing that such a procedure is certainly not giving effect to the bonus formula "but amounts to ad hoc determination which may vary according to the length of the proverbial foot of the Lord Chancellor and is bound to lead to chaos and industrial unrest. " In Workmen of India Explosives Ltd. vs Indian Explosives (1) (2) [1959] Supp. 2S.C.R. 936. 772 Ltd.(1) the labour relied on the report of the Directors which was to the effect that no income tax was payable on the year 's result and a total of Rs. 62.39 lacs made up of income tax and development rebate was being carried forward. On this report it was argued that No. deduction should be made for income tax. Negativing 'the contention it was held that in the application of the Full Bench Formula the deduction of income tax is notional	 the gross profits are arrived at by adding back certain items to the net profits and then the gross profits are reduced by making certain notional deductions	 one such deduction is under the head of income tax. It was held that this deduction is not made on the actual amount payable	 but what would be nationally payable on the profits determined under the Full Bench Formula and that if the argument on behalf of the labour were to be accepted the Tribunal would in effect not be applying the formula. Similar observations are to be found in several other decisions but we need not add them here. The question is whether the concept of notional tax liability which was adopted so long was laid aside by Parliament when it enacted section 6(c) and section 7 and replaced the concept of actual tax liability. To answer this question we must examine the scheme of the Act and Sch. Broadly speaking	 it can be safely said that Parliament has retained the main outlines of the Full Bench Formula in the Act. It maintained	 for instance	 the accounting year as the unit	 the principle that the employer	 and where it happens to be a company	 the company and its shareholders and labour as are each entitled as contributories to the profits to a share therein	 the deductions of certain prior charges	 the concept of gross profits etc. which were the features of the Formula. The principal change it introduced was the statutory formula of minimum and maximum bonus and the corollary flowing therefrom of "set on" and "set off" and the doing away of rehabilitation as a prior charge against which labour had clamored long. But do these changes envisage the doing away of the concept of notional tax liability which the Tribunals used to work out and substituting actual tax liability by first working out the taxable income of	 the employer under the Income Tax Act and other Acts ? The answer of course	 must be found from the provisions of the Act and not from what used to be done before its enactment. Sections 4	 5	 6 and 7 together with the Schedules deal with computation of gross profits and available surplus out of which 67% in cases falling under el. (a) of sec. 2(4) and 60% in cases falling under cl. (b) of that sub section would be the allocable surplus. Under Sch. II	 which applies to establishments which are not banking companies	 the starting point is the net profit (1) 773 shown by the employer in his P & L account. The reason for doing so seems to be that the Tribunal is not expected ordinarily to reopen the P & L account	 verify the accounts from which it is worked out or find. out for itself 'the true net. profit. Parliament was award that Tribunals which would adjudicate disputes under the Act would be the least efficacious for such a purpose	 apart from the fact that such enquiries would be prolonged and bitter enquiries. That is why section 23 was enacted to raise a presumption about the correctness of 'the P & L account and balance sheets of companies duly certified by auditors qualified under section 226 of the . Since the P & L account would have taken into account	 besides expenditure allowable under the Income Tax Act	 bonus payable to labour	 provisions for tax	 development rebate or development allowance and reserves	 Item 2 of Sch. II requires these amounts to be added back. Similarly	 the amounts set out in Items 3 & 4 in Sch. II are also to be added back. Item 5 provides for certain deductions ' such as capital receipts	 capital profits	 profit and receipts relating to business outside India	 income of foreign concerns from investments outside India etc. It is clear from the nature of these deductible items that they are items in which generally labour would not have made any contribution. Having thus arrived at the gross profits	 section 6 provides for deduction of prior charges Set out in cls. (a)	 (b)	 (c) and (d). Clause (a) allows the deduction of depreciation admissible under section 32 ( 1 ) of the Income Tax Act or a similar provision under other Acts charging direct taxes	 but not depreciation unabsorbed in any earlier previous year by reason of there being no profits or gains chargeable for that year or of such profits or gains being less than the allowance allowable under section 32(2) of the Income Tax Act. The result is that while making his P & L account the employer would deduct both 'the depreciation allowable under section 32(1) as. also the depreciation unabsorbed during the earlier years. The whole of Such depreciation	 however	 has to be added back under item 2(b)of Sch. II while computing the gross profits. Notwithstanding such adding back of depreciation allowable under both sub secs. 1 & 2 of section 32 of the Income Tax Act	 the depreciation deductible under s.6(a) of the Act is the one allowed under section 32(1)	 that is	 the depreciation relating to the accounting year only and not the depreciation unabsorbed in any earlier accounting year. Similar is the position regarding bonus paid during the accounting year but which relates to the earlier accounting years. Even in the case of an employer keeping his accounts on mercantile basis	 he would not get a deduction of bonus though payable but not actually paid during the accounting year. He would	 however	 be entitled to deduct such bonus from his taxable profits and gains as expenditure incurred wholly for the business. Under Sch. II Item 3(a) bonus	 even though paid during the accounting year	 has to be 774 added back if it is deducted in the P & L account. The net profit in the P & L account: would thus not be the same as the available surplus worked out under 'the Act	 The same is the position of losses and expenditure relating to a foreign business which though allowable under ' the Income Tax Act have to be added back to the net profit shown in the P & L account. As already stated deductions permissible under Sch. 11 are those items in which it can be said that labour could have made no contribution in earning them So far as development rebate is concerned	 section 6(b) allows the whole of such rebate allowable under the Income 'Fax Act and	 therefore	 there would be no difficulty in working out the development rebate under this head and the Income Tax Act. Coming now to cl. (c) of section 6	 is it the actual taxable income	 the direct tax on which is a prior charge	 which is to be worked out	 or the tax ' on the estimated balance of gross profits after deducting depreciation and development charges but without deducting the bonus payable during the year ? In other words	 when the Tribunal. reaches the stage ' of cl. (c)	 does it have to assess the taxable income in accordance with the various provisions of the Income Tax Act just as an Income Tax Officer would do and assess the liability of income tax on such taxable income according to the rates applicable during the particular accounting year	 or should it compute the balance of gross profits and as stated above and apply the said rates and estimate the amount of direct tax and deduct them from the remain gross profits? Bonus being payable within eight months after the close of the accounting year in cases.where there is no dispute pending before an authority under section 	22 of the Act as provided by section 19	 it is hardly possible	 except in rare cases	 that assessment under the Income Tax Act and other such Acts would be completed by the time bonus has to be paid; Therefore	 the Tribunal would not have before it the taxable income assessed by the Income Tax and other such officers. If the Unions ' contention were to be right	 there would be two or more parallel authorities working under this Act and the Income Tax Act and other such Acts who would have to assess taxable income and the tax payable thereon	 before all of whom the employer would have to prove his taxable income. Prima facie	 it would seem that the Bonus Act could not intend an enquiry into the actual taxable income worked out under all the elaborate provisions relating to deductions	 allowances	 reliefs	 rebates etc. provided by the Income Tax Act and other such Acts. This is particularly so as in each bonus dispute the Tribunal not equipped with the detailed knowledge of all such Acts would have to undertake an. enquiry into the various deductions	 rebates. reliefs etc. claimable by the employer under those Acts. The fact that payment of bonus cannot brooke delay without causing 775 hardship to labour would seem to militate against the possibility of such prolonged enquiries. The key to the words in section 6(c)	 namely	 "is liable to pay" emphasised on behalf of the unions and some of the interveners lies in the opening words "subject to the provisions of section 7" in cl. These words are used	 whether the tax liability is to be calculated on actual taxable income or on the notional amount worked out under sections 4 and 6 and Sch. II	 because the direct taxes payable by the employer are to be calculated at the rates applicable during that year as provided by section 7. That both such amounts cannot be the same is clear because section 7 in express terms prohibits taking into account unabsorbed losses and arrears of depreciation allowable under section 32(2)	 the exemption allowed under section 84 and the deduction allowed under section 101(1) of the Income Tax Act. Similarly	 where an assessee is a religious or charitable institution and its income either wholly or partially	 as the case may be	 is exempt under the Income Tax Act	 such an employer to whom section 32 of the Act does not apply is treated as a company in which the public are substantially interested and its income is to be assessed accordingly by the Tribunal and compute its liability for direct taxes. Clause (c) of section 7 does away for the purposes of sections 6 and 7	 the distinction between the liability of an individual and a Hindu Undivided Family under the Income Tax Act and provides that the income derived by such a Hindu Undivided Family is to be treated as the income of that employer as an individual. Likewise	 where profits and gains of an employer include profits from export	 a rebate allowed under the Income Tax Act on such profits is not to be taken into account while working out the tax. liability under section 6(c). Also	 the rebate allowed under any of the Acts levying direct taxes on sums spent on development of an industry is also not to be taken into account while computing the tax liability. It was	 however	 argued that the provisions of section 7 lay down the only departure from the Income Tax Act and that except for that departure the Tribunal must assess the actual taxable income and arrive at the tax liability thereon at rates prevailing during the accounting year in question. In our view this submission is not correct. What section 7 really means is that the Tribunal has to compute the direct taxes at the rates at which the income	 gains and profits of the employer are taxed under the Income Tax Act and other such Acts during the accounting year in question. That is the reason why section 6(c) has the words "is liable for" and the words "income	 gains and profits". These words do. not	 however	 mean that the Tribunal while computing direct taxes as a prior charge has to assess the actual taxable income and the taxes thereon. How can the Tribunal arrive at the amount of bonus to be paid to labour without first estimating the amount of taxes and deducting it from the gross profits and thus ascertaining the 776 available surplus ? If it were to reverse the process and first deduct bonus and ascertain the tax amount	 it would have to do so on a somewhat ad hoc figure thus bringing about the same result deprecated by this Court in decisions referred to above. This and the other difficulties already pointed out must deal to the result that the Tribunal must estimate the amount of direct taxes on the balance of gross profits as worked out under sections 4 & 6	 but without deducting the bonus	 then work out the quantum of taxes thereon at rates applicable during that year to the income	 gains and profits of the employer and after deducting the amount of taxes so worked out arrive at the available surplus. Section 6(c) being subject to section 7 the computation has to be done without taking into account the items specified in section 7(a) and in the manner prescribed by the remaining clauses of that section. This interpretation is commendable because: (1 ) it is consistent with the words "is liable to pay" in section 6(c)	 (2) it is in harmony with the provisions of sections 4 and 6 and Sch. 11	 and (3) it is consistent with the intention of Parliament apparent from the scheme of computation of available surplus in the Act. The Act recognises the principle laid down in the Full Bench Formula that both labour and capital are entitled to a share in the profits. That is why 40 p.o. of the available surplus is left to the capital and interest is allowed to the employer on paid up and working capitals while working out the gross profits. Parliament besides was or at any rate is presumed to have been aware that depreciation allowed under the Income Tax Act would not be sufficient for rehabilitation purposes. It did away with rehabilitation as a prior charge partly became there were complaints that it was being ill used	 but partly also because it knew that the rebate in Income Tax Act on bonus paid would go to the employer with which he could recoup the depreciation which would be larger than the one allowed under section 32 of the Income Tax Act. In our view it was for that reason that it did not lay down that bonus is to be deducted before computing the amount on which direct taxes are to be calculated under section 6(c). If Parliament intended to make a departure from the rule laid down by courts and tribunals that the bonus amount should be calculated after provision for tax was made and not before	 we would have. expected an express provision to that effect either in the Act or in the Schedules. 'In our view the contention urged by the Company that the tax liability is to be worked out by first working out the gross profits and deducting therefrom the prior charges under section 6 but not the bonus payable to the employees is right. In the result	 the appellant Company succeeds on the questions of development rebate and the provision for gratuity amount. Its appeal on those questions is therefore allowed and to that extent the award is set aside. As regards the question of depreciation 777 amount the Tribunal will ascertain the amount afresh after giving the parties opportunity to lead such evidence as they desire and taking that amount and the amounts of development rebate and ' of the provision for gratuity in the light of this judgment	 the Tribunal will adjust it award and arrive at the quantum of bonus payable to the workmen. Appeal by workmen is dismissed. There will be no order as to costs. R.K.P.S. Appeal by Company allowed in part. Appeal by Workmen dismissed.

In a dispute between the appellant and its workmen relating to the computation of bonus under the 	 the Company contended that the available surplus came to Rs. 49.96 lakhs sixty pet cent of which	 namely	 Rs. 29.98 lakhs was the allocable surplus. The employees disputed the computation claiming that the Company had wrongly reduced the gross profits and the available surplus and contended	 inter alia	 that certain amounts deducted on account of provisions for gratuity and for doubtful debts should be added back; they challenged a deduction of interest on reserves on the ground that the capital reserve was artificially arrived at by a mere revaluation of the company 's fixed assets as on April 1	 1956; and also disputed the figures of depreciation	 development rebate and direct taxes deducted by the company while working out the available surplus. The Unions disputed the amount of Rs. 28.82 lakhs worked out by the Company 's auditors as depreciation in accordance with the Income tax Act	 1961 on the ground (1) that there was no evidence that the amount of depreciation came to Rs. 28.82 lakhs; and (2) that since the profit and loss account mentioned Rs. 23.48 lakhs as depreciation	 the Company could only claim that amount. In its award the Tribunal allowed Rs. 23.48 lakhs instead of Its. 28.82 lakhs claimed by the company as depreciation. Similarly it allowed only Rs. 7 lakhs instead of Rs. 8.8 lakhs claimed by the company as development rebate. The Tribunal held that the amount of Rs. 18.38 lakhs claimed under the head of gratuity was not a reserve but a provision and therefore	 was not liable to be added back	 but it held that the company could deduct only about Rs. 10 lakhs as also Rs. 1.31 lakhs and Rs. 87	000/ actually paid during the year to employees who retired during that year and added back the balance of Rs. 6 lakhs to the gross profits. Except for these amounts	 the Tribunal accepted the rest of the company 's computation. Both the Unions and the Company obtained special leave and fled appeals challenging the correctness of the Tribunal 's award. In their appeal it was also contended by the Unions that the Tribunal had wrongly allowed a deduction of Rs. 145 lakhs as direct taxes under sec. 6(c); all that the employer could deduct was direct taxes which he "is liable to pay" for the accounting year in respect of "his income	 profits and gains during that year"	 i.e.	 the employer is entitled to deduct only his actual tax liability. Such liability. therefore	 has to be worked out in accordance with the provisions of the Income tax Act and other relevant Acts by first arriving at the actual taxable income	 gains and profits under those Acts and then compute the taxes at rates provided by them for that particular accounting year. 751 HELD:The appellant.company contentions on the questions of development rebate and the provisions for gratuity must be upheld; the amount of depreciation must be ascertained afresh by the Tribunal after giving the parties opportunity to lead such evidence as they desired. The ' workmen 's appeal must be dismissed. (1) The depreciation deducted in the expenditure column in the Profit and Loss Account was the depreciation worked out under section 205(2) of the Companies Act	 but under section 6 of the Bonus Act	 the Company is entitled to deduct from its gross profits depreciation admissible under Section 32(1) of the. Income tax Act	 i.e.	 such percentage on the ' written down value as may	 in the case of each of the classes of assets	 be prescribed. It was for this reason that Rs. 23.48 lakhs were shown as depreciation in the Profit and Loss Account by the Company while in the computation for bonus the company claimed Rs. 28.82 lakhs as. depreciation. [755 H 756 B] Since the Company claimed the deduction of depreciation	 the burden of proof that the amount claimed was in accordance with the Income tax Act was on the Company and that burden the company must discharge once its figures were challenged. It was not sufficient for it to produce its auditors ' certificates. The question as to the correct amount of depreciation must therefore go back to the Tribunal for a further decision. The Tribunal must give an opportunity to the Company to prove its claim for depreciation by reasonable proof and to the Unions to test such	 evidence by cross examination or otherwise.

(2) Under section 6(b) of the Bonus Act the Company is entitled to deduct out of the gross profits arrived at under section 4 the whole of the development rebate admissible under the Income tax Act	 i.e.	 the amount	 75 per cent of which comes to Rs. 7 lakhs in the present case. The Tribunal was in error in mixing up the development rebate reserve to which the Company had to appropriate Rs. 7 lakhs in the Profit and Loss Account and the development rebate of Rs. 8.87 lakhs allowable to it under section 6. of the Act. There was therefore no justification for the Tribunal to allow ' Rs. 7 lakhs only instead of Rs. 8.87 lakhs as development rebate. [759D F] (3) An estimated liability under gratuity schemes as in the present case	 even if it amounts to a contingent liability and is not a debt under the Wealth Tax Act	 if properly ascertainable and its present value is fairly discounted	 is deductible from the gross receipts while preparing the Profit and Loss Account. This is in accordance with accepted principles of commercial practice and is also the position under the Income tax Act. There is no rule or direction in the Bonus Act which prohibits such a practice. [766 C; 767 D] The Tribunal in allowing Rs. 10 lakhs out of the estimated liability of Rs. 16 lakhs impliedly accepted the same principle but allowed only Rs. 10 lakhs because it thought the estimate to be excessive. This was not done on the ground that the estimate of Rs. 16 lakhs was not warranted on any valuation. In the absence of any challenge as to the correctness of the valuation and in the absence of any challenge that such iiability cannot be estimated on any fair standard. the Tribunal ought to have allowed the whole of Rs. 16 lakhs to be deducted while arriving at the net profits in the Profit and Loss Account.

(4) There was no justification for the contention that revaluation of company 's assets in 1956 was fictitious and that the difference of Rs. 57 lakhs was a mere hook adjustment and did not add to the wealth of the company so that no deduction by way of interest was permissible on such an artificial amount. [767 H] In the present case the revaluation was made as early as 1956 and did not appear to have been objected to at any time either by the Company 's auditors or by any one else concerned with the Company 's management. It cannot	 therefore	 be legitimately said that it was done for any oblique purpose	 much less with a view to defeat the labour 's claim to bonus. It is true that such revaluation does not bring in any tangible additional amount into the company 's coffers which it can use for its business. But under sec. 211 of the Companies Act	 every balance sheet of a company must give a true and fair view of the state of affairs of the company as at the end of the financial year. VI to the Companies Act also provides that where sums have been written off on a reduction of capital or a re valuation of assets	 the balance sheet	 subsequent to such reduction or revaluation must show the reduced or the increased figures as the case may be. Apart from the provisions of the Companies Act	 it is a recognised principle of accountancy to transfer the increased value of assets on revaluation to a capital reserve account. Such an increased figure is an unrealised accretion in the value of a fixed asset. The fact that such an increased figure does not actually bring in any additional amount to the company does not make the capital reserve any the less a reserve. [768 C G] The Tribunal was therefore right in accepting the figure of Rs. 57 lakhs and deducting interest thereon from the gross profits. (5) Bonus being payable within eight months after the close of the accounting year in cases where there is no dispute pending before an authority under section 22 of the Act as provided by section 19	 it is hardly possible	 except in rare cases	 that assessment under the Income tax Act and other such Acts would be completed by the time bonus has to be paid. Therefore	 the Tribunal would not have before it the taxable income assessed by the Income tax and other such officers. If the Union 's contention were to he right	 there would be two or more parallel authorities working under the Bonus Act and the Income tax Act and other such Acts who would have to assess taxable income and the tax payable them	 before all of whom the employer would have to prove his taxable income. In each bonus dispute	 the Tribunal	 not equipped with the detailed knowledge of all such Acts	 would have to undertake an enquiry into various deductions	 rebates	 reliefs	 etc. claimable by the employer under those Acts. The fact that payment of bonus cannot broke delay without causing hardship to labour would seem to militate against the possibility of such prolonged enquiries. [774 E 775 A] An examination of the provisions of the Bonus Act shows that the 'Tribunal must estimate the amount of direct taxes on the balance of gross profits as worked out under sections 4 and 6	 but without deducting the bonus	 then work out the quantum of taxes thereon at rates applicable 	during that year to the income	 gains and profits of the employer and 753 after deducting the amount of taxes so worked out arrive at the available surplus. Section 6(c) being subject to section 7 the computation has to be done without taking into account the items specified in section 7(a) and in the manner prescribed by the remaining clauses of that section. This interpretation is commendable because; (1) it is consistent with the words "is liable to pay" in section 6(c)	 (2) it is in harmony with the provisions of sections 4 and 6 and Sch. H	 and (3) it is consistent with the intention of Parliament apparent from the scheme of computation of available surplus in the Act. Furthermore	 if Parliament intended to make a departure from the rule laid down by courts and tribunals that the bonus amount should be calculated after provision for tax was made and not before	 it would have made an express provision to that effect either in the Act or in the Schedules.
