THE FACTUAL BACKGROUND
3 Transurban was what the learned Primary Judge described as "the project vehicle" for the City Link Project, the largest urban infrastructure project in Australia. The project involved the design and construction of a road link connecting three of the four main Melbourne freeways which then ended at the City fringe, those being the Monash Freeway (formerly the South Eastern Freeway), the Tullamarine Freeway and the West Gate Freeway. As originally devised the City Link involved only the Western Link and the Southern Link. Subsequently a third element known as "the Elizabeth Street Extension" was added. That addition was the subject of a separate agreement made in April 1998. Once the road links were completed the project contemplated that the road links would be operated with toll being collected at certain points using an electronic toll collection system until ultimately the road links would be surrendered to the State of Victoria.
4 The Victorian government called for bids for the project in 1994. A consortium of Transfield Holdings Pty Limited ("Transfield") and Obayashi Corporation ("Obayashi") was the successful tenderer. On 20 October 1995 a Concession Deed was executed between Transurban, the State and other parties. It was under this Deed that the amounts claimed to be deductible arose. Between the date of the Concession Deed and 28 June 2002 there, were, as the learned Primary Judge noted, 17 further deeds executed amending the concession agreement. Most are irrelevant to the present appeal.
5 The western links and parts of the Exhibition Street extension opened to traffic during 1999 but tolling only commenced in respect of the western link on 3 January 2000. Tolling commenced on the west bound sections of the southern link on 26 April 2000 and on the in-bound end of the Elizabeth Street Extension on 1 July 2000. Under the Concession Deed the concession period commenced from the date on which there was "financial closing", namely 4 March 1996 and continued unless otherwise determined for 33 years and 6 months after the "City Link Expected Completion Date" which was 14 July 2000. Accordingly, in the normal course, the concession period would be expected to continue until 14 February 2034.
6 It was the responsibility of the State of Victoria, inter alia to contribute land for the purposes of the project, and to coordinate approvals from State authorities to enable the link to be constructed and operated. This involved, inter alia, the State acquiring land for the project which would, upon acquisition become Crown Land and then be made available to Transurban under licences which were to be issued by the Melbourne City Link Authority. Importantly the State was obliged to provide the necessary legislative framework for the project. The legislation provided for the levy of tolls and created an offence of evading payment of tolls, which offence became subject to penalty. The legislation enacted was the Melbourne City Link Authority Act 1994 and the Melbourne City Link Act 1995 (Vic). The latter Act received the Royal Assent on 12 December 1995. In summary that Act ratified the Concession Deed, as if enacted and provided what may be referred to as legislative support for various aspects of the City Link project.
7 It is necessary now to summarise the relevant provisions of the Concession Deed. Many of these provisions are set out in greater detail in the judgment of the learned Primary Judge. It is unnecessary to repeat them here except to the extent that they are relevant to the issues in the appeal.
8 The objectives of the Concession Deed are set out in Clause 2. Among these, which include the integration of the road link project into Melbourne's road system, is the intention that project debt be repaid in accordance with lending documents and that equity investors in the project derive at least a base case equity return. The obligation of Transurban was to finance design and construct the Link and to operate, maintain and repair it.
9 By virtue of Clause 2.8 of the Concession Deed the State granted to Transurban the right to design, construct, commission and operate the Link road, to impose and collect a toll, maintain and repair the roads and raise revenues from other lawful uses of the Link as approved by the State. The Concession was to be continued, but subject to the Concession Deed until the end of the Concession Period. This was, essentially, 33 ½ years, although that period could in certain events be reduced to 25 ½ years or in the event of the happening of a materially adverse circumstance it could be increased to 53 ½ years.
10 Critical to the present appeal is clause 3 of the Concession Deed. The clause provides, relevantly, as follows:
(a) (i) "The Companyshall (provided the Concession Period then continues), in consideration of the State granting the concession rights set out in clause 2.8, pay to the State in the period from the date of the commencement of the Concession Period until the end of the twenty-fifth year after the date which is 6 months earlier than the Link Expected Completion Date an annual concession fee of $95,600,000, payable in equal instalments semi-annually in arrears, on the last Business Day of each June and December in that period and on the date of termination of this Deed (should termination occur in that period) with each such payment being adjusted on a pro rata basis for any period of less than 6 months.
(ii) The Company shall (provided the Concession Period then continues), in consideration of the State granting the concession rights set out in clause 2.8, pay to the State in the period from the date of the commencement of the twenty-sixth year after the date which is 6 months earlier than the Link Expected Completion Date until end of the thirty fourth year after that date an annual concession fee of $45,200,000, payable in equal instalments semi-annually in arrears, on the last Business Day of each June and December in that period and on the date of termination of this Deed (should termination occur in that period) with each such payment being adjusted on a pro rata basis for any period of less than 6 months;
(iii) The company shall (provided the Concession Period then continues), in consideration of the State granting the concession rights set out in clause 2.8 pay to the State in the period from the date of the commencement of the thirty fifth year after the date which is 6 months earlier than the Link Expected Completion Date until the date of termination of this Deed, an annual concession fee of $1,000,000 payable in equal instalments semi-annually in arrears on the last Business Day of each June and December in that period and on the date of termination of this Deed, with each such payment being adjusted on a pro rata basis for any period less than 6 months.
(b) The Company shall pay to the State rent under the Company Leases and the Trustee shall pay to the State rent under the Trust Leases and the Trust Concurrent Leases, as provided for in those Leases.
(c) The Company and the Trustee shall pay to the State on demand reasonable costs and expenses incurred or payable by the State:
(i) in exercising powers under clause 9.11;
(ii) in it or any Victorian Government Agency taking reasonable measures outside the Project Land or to manage traffic outside the Project Land, to the extent required under arrangements approved under clause 7.13(a), to be taken by it or a Victorian Government Agency under the Project Scope and Technical Requirements;
(iii) in it or any Victorian Government Agency taking measures to deal with the effects of any interference with the flow of traffic on roadways in the vicinity of the Project Land, the Lay Down Areas or the Off-Site Areas caused by the Works or the operation or maintenance of the Link being measures reasonably taken if the State has been (or should have been), in accordance with this Deed, requested by the Company or the Trustee to deal with the interference;
(iv) in making a payment pursuant to the Contractors' Deed of Novation to remedy or overcome the consequences of a Construction Contract Default (as that expression is defined in the Contractors' Deed of Novation).
(d) The Company shall pay to the State as an additional concession fee a proportion of the amount by which the aggregate revenue derived by the Company (or any of its subsidiaries), in any relevant period exceeds that projected in the Base Case Financial Model. Such a payment need only be made if the actual cumulative real after tax return which a Notional Initial Equity Investor would be considered to have derived on its investment in Project Securities up to the end of that period exceeds the cumulative real after tax return which a Notional Initial Equity Investor was projected by the Base Case Financial Model to have received on its investment in Project Securities up to the end of that period."
11 Clause 3.4 provided that at the end of the Concession Period Transurban and the party referred to as "the Trustee" under the Agreement were to surrender the Link and deliver to the State all plant and equipment in essence relevant to the project.
12 By virtue of Clause 7.8, Transurban was bound to construct the Link so that it was fit for its intended purposes. Completion was to take place by the "Link Expected Completion Date". Clause 9 set out the obligations of Transurban during the Concession Period to operate each section of the Link including the tolling system. Clause 10 dealt with the obligations of Transurban during the Concession Period to maintain and repair the Link. Land of or acquired by the State was to be the subject of licences in the construction period or crown leases in the operation period, either to Transurban or the Trustee and in the latter case sub-leased to Transurban. Rental was payable at the nominal rate of $100 per annum.
13 Under Clause 15 of the Concession Deed the State could, in certain events, which may generally be described as events of default, terminate the Concession Deed.
14 As may be expected, the financing details of the project were very complicated. It suffices here to state that the State had a deed of charge imposed by what was referred to as "the Master Security Deed" to secure the obligations to the State under the various agreements. Following an amendment to the charge documents, clause 1.9 of the Master Security Deed provided:
" 1.9 Payments by the Company or Trustee
For so long as any Project Debt is owing and notwithstanding the express terms of any Project Document to the contrary, any payment to be made by the Company or the Trustee to the State under, or for breach of, any Project Document (other than payment of the State's Priority Amount) (the "State Payment Amount") shall be owing to the State but shall not be due for payment until sufficient money is available for withdrawal from the Distributions Account (as defined in the Security Trust Deed) to meet that payment in full and each of the Company and the Trustee undertakes not to apply any amounts held in the Distributions Account maintained in its name for any purpose other than payment of that State Payment Amount until the balance of the Distributions Account maintained in its name equals or exceeds that State Payment Amount to the extent that it is not in dispute and all or part of the balance has been applied by it to pay that State Payment Amount in full to the extent that it is not in dispute.
…"
15 Clause 18.5 of the Master Security Deed provided that the obligation of Transurban to pay an amount payable under paragraph 3.1(a) of the Concession Deed, that is to say the Concession Fee could, at the election of Transurban "be satisfied" by Transurban issuing to the State (on or before the due date for payment of the amount) Concession Notes having a face value of the amount payable. The contemplation seems to be that such notes would be issued in multiples of $100,000. A Concession Note was to be in the form set out in an exhibit to the Concession Deed. That Exhibit, as amended in 1996 provided, relevantly:
"Part 2 Amount of Concession Note
Upon presentation for payment in accordance with this Concession Note, the Company in its own capacity and for valuable consideration promises to pay the Crown in right of the State of Victoria the sum of $ ("Payment Amount") being the liability of the Company incurred under Article 3.1(a) of the Concession Deed in respect of the Concession Fee payable for the semi-annual period ending on for the financial year ended 30 June .
Part 3 Payment of Concession Notes
(a) The Payment Amount must be paid under this Concession Note notwithstanding paragraphs (b) and (c), on the date which is 33 years and 6 months after the Link Expected Completion Date ("the Expiry Date") and this Concession Note may be presented for payment to the Company at any time after 32 years and 6 months after the Link Expected Completion Date.
(b) If the following conditions have been satisfied at any time prior to the Expiry Date:
(i) the Equity Return (determined as at a date not earlier than 4 months before presentation of this Concession Note and as if the Concession Period ended on that date) must be 10% per annum or more; and
(ii) the payment of the Payment Amount under this Concession Note must not result in the aggregate of the amounts paid by the Company under the Concession Notes, and of the amount payable under this Concession Note, presented in the financial year in which this Concession Note is presented, exceeding 30% of the Distributable Cashflow for the preceding financial year. This Concession Note must be paid on the later of the date which is 30 days after presentation by the State for payment and the date which is the earlier of:
(A) 30 days after the finalisation of the financial accounts of the Company and Trust for the financial year preceding the financial year in which this Concession Note is presented; and
(B) 3 months after the end of the financial year preceding the financial year in which the Concession Note is presented.
(c) If the Concession Period ends prior to the Expiry Date:
(1) due to the operation of paragraph (a) of the definition of Concession Period, then this Concession Note must be paid on the Expiry Date; or
(2) otherwise, and if the conditions of paragraph (b) above have been satisfied, this Concession Note must be paid within 30 days after presentation by the State for payment.
Part 4 Manner of Presentation
(a) This Concession Note may only be presented for payment by the State or its delegate appointed under clause 1.5 of the Concession Deed at Level 2, 437 St Kilda Road, Melbourne or such other address in Melbourne notified in writing for this purpose by the Company to the State.
(b) Unless clause 1.9 of the Master Security Deed is then applicable to this Concession Note, then for so long as any Project Debt is owing and notwithstanding any express terms of this Concession Note to the contrary any payment to be made by the Company under, or for breach of, this Concession Note shall be owing but shall not be due for payment until sufficient money is available for withdrawal from the Distributions Account (as defined in the Security Trust Deed) to meet that payment in full after paying all amounts owing to the State under, or for breach of, a Project Document (other than any Concession Note) or owing under or for breach of, any Concession Note having a prior number to this Concession Note.
Part 5 Concession Note transferable
This Concession Note is transferable and does not bear interest."
The expression "Equity Return" was defined in the Concession Deed to be "the expected real after tax internal rate of return which a Notional Initial Equity Investor is projected to receive on its investment" (using a model provided for in the Deed) of 10 per cent per annum or more.
16 The "distributions account" referred to both in Clause 1.9 of the Concession Deed and in the Concession Notes was an account required to be maintained by Transurban. A similar account was required to be kept by the Trustee for investors. The sources of the funds to be channelled into the account were funds that had reached a clearing account and funds in an excess cash flow account. The Deed provided that Transurban could transfer funds from the clearing account to the distributions account for the purpose of paying amounts to the State and from the excess cash flow account to the distribution account subject to debt ratios being maintained. Tolls and other project revenue, as well as loan draw downs were ultimately to be deposited in the clearing account. Certain amounts such as funding costs, mandatory repayments, operating, maintenance and construction costs were permitted to be transferred out of the clearing account. What was ultimately to be transferred to the distributions account was, generally speaking, therefore, project cash receipts less outgoings associated with the operation and maintenance of the Link. The purpose of the distribution account was to faciliate payment of amounts owing first to the State and then to any other person to whom an amount was owing under a Concession Note. It was only when these obligations were met that the funds in the distribution account could be used by Transurban.
17 Accordingly, all outstanding Concession Notes were redeemable by the State within 33 years and 6 months after the "Link Expected Completion Date." In fact Transurban issued Concession Notes to the State of Victoria for the concession fees payable in each of the years of income and indeed for all subsequent concession fees. It may be assumed that this provided a mechanism for the State to assign the notes to investors should it desire to do so and thus obtain an earlier but no doubt discounted, return.
18 As noted by the learned Primary Judge the effect of the provisions of the agreement was that presentation of the Concession Notes could not occur while Project Debt was outstanding unless there was sufficient money in the Distributions Account to meet the payment in full. Under the Base Case Model used in the agreements, redemption of the Concession Notes was expected to commence in November 2013 and Project Debt was expected to be repaid by 2023. The earliest day on which payments were likely to commence was 2013. A model prepared by financiers expected payments to commence in 2017. In fact, as events have happened traffic volumes on which both models were based fell short of projections with the consequence that currently redemption was not expected to commence until closer to 2034.
19 The Master Security Deed also dealt with matters of priority as between the "Security Trustee" which acted on behalf of financiers of the project and obligations owed to the State. Other priority provisions are to be found in a Security Trust Deed entered into between Transurban and the City Link Project financiers. It suffices to say that the State generally had priority in respect of amounts owing to it. However the Concession Notes were excluded from state priority.
