1 SPIGELMAN CJ: I agree with Meagher JA and with Powell JA.
2 MEAGHER JA: The plaintiff ("Morgan") appeals against a judgment by Foster AJ given on 7 May 2001. It is a Californian company which has its principal place of business in California. It had sued the defendant UMW Corporation, a Malaysian corporation, the present respondent. The litigation arises out of the sale by Morgan, in 1993, to UMW of the whole of the issued share capital in its wholly owned subsidiary Morgan Equipment Pty Ltd ("MEPL"), which was a company incorporated and carrying on business in Papua New Guinea.
3 The sale was the subject of a written agreement dated January 1993, (which has subsequently been amended once, although in an immaterial respect). The business of MEPL was the selling and servicing of heavy equipment. From time to time it made trade losses which could be carried forward and used as a deduction against profits in future years in accordance with the revenue laws of Papua New Guinea, which in this respect were the same as the laws of Australia. The agreement made provision for the sale of such losses. The terms of this sale and purchase were the subject of a separate régime contained in the agreement, although the price is not contained in the general price for the sale of the MEPL shares.
4 The clauses of the agreement which require consideration in this appeal are clauses 1(g), 2(b), (g), (n), (z), (aa), and 5(c). These must be set out in full:
"1. INTERPRETATION
(g) where any word or phrase is given a defined meaning in this Agreement, any other part of speech or other grammatical form in respect of such word or phrase shall have a corresponding meaning.
2. DEFINITIONS
(b) "Accounts" means the Company's audited balance sheet, profit and loss account drawn to the Accounting date, annexed as Exhibit A, including all applicable notes, statements and reports of directors and auditors;
(g) "Completion" means actual completion of the sale and purchase of the Sale Shares in accordance with the terms of this Agreement;
(n) "Income Tax Act" means the Income Tax Act 1989 of the Independent State of Papua New Guinea;
(z) "Tax Loss Carry Forward" means losses of the Company whether reflected in the Accounts, the books and records or the tax returns of the Company, which losses result in tax credits which can be utilized against payment of income tax in Papua New Guinea;
(aa) "Taxes" includes all taxes levied or assessed pursuant to the Income Tax Act or any other statute, ordinance or law, in Papua New Guinea or elsewhere, sales tax, payroll tax, group tax, PAYE, undistributed profits tax, land tax, water rates, municipal rates, stamp duties, gift duties or other provincial, or municipal charges or impositions together with any penalties of any kind assessed, charged or imposed in respect of the non late or short payment of the same;
5(c) In addition to the Purchase Price, and as part of the consideration for the Sale of Shares, the Purchaser agrees to pay to the Vendor, or its successors and assigns, a sum calculated as follows and subject to the provisions of this clause 5(c):
(i) The Purchaser will pay to the Vendor an amount calculated as follows:
50% of the Tax Loss Carry Forwards, multiplied by the applicable effective tax rates, as stated on the tax returns of the Company as at December 31, 1991, subject to adjustment for additional tax loss carry forwards which are accrued on the books and records of the Company through the Completion Date, if any.
(ii) Payments under clause 5(c)(i) will be due upon utilization of the tax loss carry forwards by the Company or upon a finding that taxable income should be imputed to the Company and thus subject to payment hereunder . For purposes of this Agreement, utilization will occur upon the filing of a tax return of the Company wherein a tax loss carry forward is used to reduce or eliminate the amount of Taxes payable by the Company . An imputation of taxable income would occur if, for example, the Purchaser or the Company engaged in actions reasonably calculated to transfer or reduce taxable income in Papua New Guinea in a manner inconsistent with the prior operating procedures of the Company. An imputation should not be made if such actions of the Company are consistent and in accordance with the then subsisting operating procedures of other companies owned or controlled by the Purchaser. In this regard, Purchaser shall be entitled to assert interest charges incurred by the Purchaser on behalf of the Company and a management fee not to exceed 1.5% of annual sales of the Company.
(iii) In this regard, the Vendor will have the absolute right to inspect and audit the tax returns, books and files, including internal accounting records, of the Company and any other accounting, tax or other records of the Purchaser or its subsidiary corporations or entities to the extent that such records specifically relate to the Company and, if appropriate, to impute the income which was derived from the operations of the Company but were not accounted for in such a manner as described in Clause 5(c)(ii) above so as to constitute taxable income in Papua New Guinea.
(iv) For purposes of this Agreement, and in direct reference to the Company and the relevant tax laws of Papua New Guinea as the same shall apply, provided always that the tax loss carry forwards if utilizable and in respect of which payment is to be made to Vendor or its successors or assigns hereunder, shall have to be utilized within a period of seven (7) years from the date they were first incurred, unless the laws and regulations of Papua New Guinea are amended to provide for a different period of utilization, in which case the appropriate period set forth in amended laws or regulations shall apply.
(v) The Purchaser will cause the Company to reflect the Tax Loss Carry Forwards on the books and records of the Company and its tax returns. The Purchaser will cause the Company to take all steps necessary to preserve and qualify the Tax Loss Carry Forwards. In no event will the Purchaser be required to make payment under this clause 5(c) unless the Tax Loss Carry Forwards are recognized as valid under the provisions of the Income Tax Act or in the event that the Company utilizes any portion of the Tax Loss Carry Forwards in the payment of Taxes payable by the company which payment is related to the Asset Sale Agreement and the transactions contemplated therein.
(vi) The parties acknowledge that there have been writedowns of certain of Sale Assets on the books and records of Company which will create additional Tax Loss Carry Forwards. The Purchaser will cause the Company to reflect said Tax Loss Carry Forwards on the books and records of the company and its tax returns. The Purchaser will cause the Company to take all steps necessary to preserve and qualify these Tax Loss Carry Forwards. However, in the event that the Tax Loss Carry Forwards referred to in this clause 5(c)(vi) are not recognized as valid under the provisions of the Income Tax Act, the Purchaser will not be required to make payment therefore and shall not be held responsible to the Vendor in such an event."
5 The "effective tax rate" referred to in clause 5(c)(i) is 25%.
6 There is what Foster AJ called a "tension" between 5(c)(ii) and 5(c)(v). The former seems, at first blush, to say that payments must be made, subject to certain conditions, on the filing of an income tax return, the latter that no payments are due until the company receives its income tax assessment. The former view was favoured by Morgan, the latter by UMW. The trial judge found in favour of the latter.
7 Some evidence was admitted by his Honour to clarify the meaning of the expression "upon the filing of a tax return by the Company wherein a tax loss carry forward is utilized" in clause 5(c)(ii). This is best illustrated by an example. In the Company's tax return for the period ending 31 December 1989 there is a document consisting of a series of calculations concluding with the words "Income Tax Loss - K397,632", followed, at the foot of the page, by the words "Please confirm the loss carried forward."
8 There was another document, issued by the Papua New Guinea tax authority, which obviously refers to the preceding document. It contains the sentence "Loss Carry-Forward is K397,632". His Honour drew the obvious inference, saying: "I am satisfied that document 493 is, relevantly, an indication from the taxation authority that the income tax loss shown" in the previous document "was confirmed as being a loss carried forward in that amount."
9 Other pairs of documents show similar results for other years.
10 The canons of construction relevant to the interpretation of the Agreement are hardly in dispute, but of particular importance is the rule that one must construe a document as a whole so as to yield an "harmonious", not an unworkable, reading. To this end, his Honour gave primacy to the provisions of cl 5(c)(v). The Appellant contended that the words in cl 5(c)(v) 'recognised as valid' refer to the document described as an Adjustment Sheet of the character identified in par [8] above. However as Foster AJ concluded unless such an Adjustment Sheet issues, a loss cannot be utilised against payment of income tax and, accordingly, there is no 'Tax Loss Carry Forward' within cl 2(z). Accordingly, cl 5 including cl 5(v) proceeds on the assumption that an indication of the character identified in an Adjustment Sheet has been made. The words 'recognised as valid', refer to the point of time at which loss is reflected in an assessment. His Honour was quite correct in this regard.
11 The obvious objection to this construction is that it involves the elimination of the second sentence of clause 5(c)(ii). However, I do not think this objection can be sustained. One permissible use of the preposition "upon" is to mean "as a result of", and that in my view is how it is used here. One then has an "harmonious" whole: a claim is made, it is "utilized" when it is provisionally accepted or "utilized", and it results in a liability to pay when an assessment reflecting it is issued. There thus cannot follow the complications, which might occur if a loss once "confirmed" is later disallowed.
12 In my view the appeal should be dismissed with costs.
13 POWELL JA: This is an appeal against a Judgment delivered, and orders made, by Foster AJ on 7 May 2001 on which day his Honour dismissed with costs the proceedings which had been brought by the Appellant ("Morgan") against the Respondent ("UMW") and directed the entry of Judgment accordingly.
14 In those proceedings, Morgan sought to recover from UMW a sum of money which it claimed to be owing to it pursuant to the terms of an Agreement entered into between itself and UMW in January 1993.
15 By that Agreement (Blue AB 18-67) - which Agreement was amended in an immaterial way by a further Agreement executed on 30 March 1993 (Blue AB 68) - Morgan, as vendor, agreed to sell and transfer to UMW, and UMW agreed to purchase from Morgan, the whole of the issued shares in Morgan's then wholly owned subsidiary, Morgan Equipment Pty. Limited ("MEPL"), a company incorporated, and carrying on business, in Papua New Guinea, for the sum of US$3,706,899.00. Although the Agreement was directed primarily to the sale and transfer of those shares, the Agreement also made provisions, in the circumstances set out in clause 5(c) for payment by UMW to Morgan of sums to be calculated in respect of what were described as "Tax Loss Carried Forwards".
16 Insofar as bore upon the claim made by Morgan in the proceedings with which Foster AJ was concerned to deal, the Agreement provided as follows (Blue AB 18-20, 24-25):
"1. Interpretation

………
(g) where any word or phrase is given a defined meaning in this Agreement, any other part of speech or other grammatical form in respect of such word or phrase shall have a corresponding meaning.
………
2. Definitions
In this Agreement unless otherwise expressly provided:
………
(n) 'Income Tax Act' means the Income Tax Act 1989 of the Independent State of Papua New Guinea.
