Compound interest.
22 In Hungerfords v Walker (1988-1989) 171 CLR 125 it was held that damages for breach of contract might include compensation for loss of use of money a party has paid out as a result of the other party's breach and those damages in the nature of interest can be calculated as compound interest.
23 In that case evidence was adduced with respect to the loss sustained by the party paying out as a result of the other party's breach. No evidence of loss as a result of the failure of Hannover to pay on reconsideration of the claim was adduced in this case.
24 In Hobartville Stud Pty Ltd v Union Insurance Co Ltd (1991) 25 NSWLR 358 at 363-364, Giles J held that it remains necessary to undertake a factual investigation into the loss suffered through being held out of money. Whether a plaintiff would have made a profit from the use of money withheld from it and the amount of that profit must be determined on the evidence. There is no automatic allowance of interest upon money withheld.
25 In the absence of evidence I am not prepared to grant Mr Dumitrov damages in the nature of interest by an award of compound interest under the Insurance Contracts Act 1984 (Cth), s 57(1).
26 In Membrey at [43], Crennan J said there was nothing in the Insurance Contracts Act 1984 (Cth), s 57 that would preclude the awarding of compound interest on appropriate facts in an appropriate case.
27 The specialist tribunal in that matter inferred that the insurer had earned profits from the investment of the moneys in question and awarded compound interest. That is the distinguishing feature from this case. The court is not a specialist tribunal and no evidence was adduced with respect to damages in the nature of interest. I adopt the approach taken by Giles J in Hobartville.
28 In Moss v Sun Alliance Australia Ltd (1990) 55 SASR 145, Bollen J drew a distinction between interest and damages in nature of interest and concluded that the Insurance Contracts Act 1984 (Cth), s 57 did not deal with that question. Giles J adopted that view in Hobartville and explained that Tatt was concerned with interest and not damages in the nature of interest.
29 On that analysis there may be a problem in construing the Insurance Contracts Act 1984 (Cth), s 57 as extending beyond statutory interest and encompassing damages in the nature of the interest. I do not have to decide that question, however, because I am of the view that whether or not compound interest is recoverable under s 57, it requires the adducing of evidence upon which quantification can be made and there was no such evidence in this case.
30 Ms Dulhunty called in aid those cases in which compound interest has been awarded where a fiduciary has been in gross breach of duty (Harris v Digital Pulse Pty Ltd (2003) 56 NSWLR 298, Harrison & Anor v Schipp; Cameron & Anor v Schipp [2001] NSWCA 13).
31 But Hannover was not a fiduciary. It entered into a commercial contract with the trustee. In Trident General Insurance Co Ltd v McNiece Bros Pty Ltd (1987-1988) 165 CLR 107 two members of the High Court adopted the view of the majority of the Court of Appeal in Trident General Insurance Co Ltd v McNeice Pros Pty Ltd (1987) 8 NSWLR 270 in concluding that there should be an exception to the doctrine of privity with respect to a person who, though not a party to a public liability insurance policy, fell within the class of persons expressed to be insured by it, such that such a person might enforce the indemnity for which the policy provided. Deane J considered that the non-party was not entitled to enforce the indemnity but should be afforded an opportunity to establish that the policy created a trust in that person's favour of the benefit of the insurer's promise to identify it. Those alternative bases for the majority decision in Trident were recognised by Hunter J in Wyllie v National Mutual Life Association of Australasia Ltd (1997) 217 ALR 324.
32 It follows that reliance upon those authorities that establish the proposition that compound interest is an appropriate order where a fiduciary is in gross breach of duty do not support an award of compound interest, either under the Insurance Contracts Act 1984 (Cth), s 57 or at common law, as damages in the nature of interest for a breach of a contractual term by Hannover under a policy to which Mr Dumitrov was not a party.
33 In my view, Mr Dumitrov has failed to establish an entitlement to compound interest and is confined to a simple interest calculation under the Insurance Contracts Act 1984 (Cth), s 57.
Quantification
34 The Insurance Contracts Regulations (Cth), reg 32 prescribe the manner in which interest is to be calculated. It provides as follows:
"(1) For subsection 57 (3) of the Act, the rate applicable to a day in respect of which interest is payable by an insurer, is the rate worked out under the following formula:
Y + 3%
where:
Y is the rate of:
(a) 10-year Treasury Bond yield at the end of the half-financial year ending in the period that, in relation to the withheld amount, is mentioned in subsection 57 (2) of the Act, or:
(b) if more than one half-financial year has ended during that period-the mean of the rates of the 10-year Treasury Bond yield at the end of each of those half-financial years; or
(c) if no half-financial year has ended during that period-the 10-year Treasury Bond yield at the end of the half-financial year immediately preceding the commencement of that period.
(2) In subregulation (1), 10-year Treasury Bond yield means the rate known as the 10-year Treasury Bond yield, published by the Reserve Bank of Australia.
(3) In subregulation (1), mean , in relation to rates, means, if the mean of the rates is not a whole number, or does not end in .75, .50 or .25, the mean rate rounded to the nearest lower quarter of 1%."
35 Ms Dulhunty submitted the appropriate way to calculate interest was to round down the 10-year Treasury Bond yield for each half-financial year to the nearest lower quarter of 1%, add 3% and apply that rate to the half-financial year.
36 Mr Horsley submitted that one should take the 10-year Treasury Bond yield at the end of each half-financial year in the period from 25 September 2002, obtain the arithmetical mean, round it down to the nearest lower quarter of 1%, add the 3% margin and apply the resultant rate to the number of days between 25 September 2002 and the date of judgment.
37 In my view, Mr Horsley's approach is the correct one. Since more than one half-financial year has ended in the period from 25 September 2002, the Insurance Contracts Regulations (Cth), reg 32(1)(b) requires the arithmetic mean of the rates at the end of each of those half-financial years to be determined.
38 Mr Horsley arrived at a rate of 8.25%. The last half-financial year he took into account ended on 31 December 2006. Mr Horsley took this approach on the basis that the interest should be calculated from 25 September 2002 to judgment. I do not disagree with this approach. The question remains, however, what interest should be paid on the judgment?
39 In Fruehauf Finance Corporation Pty Ltd v Zurich Australian Insurance Ltd (1993) 32 NSWLR 735, Giles J rejected a submission that interest after judgment was governed by the forerunner of the Civil Procedure Act 2005, s 101. His Honour adverted to the fact that the Insurance Contracts Act 1984 (Cth), s 57(2) made it clear that the period for which interest under that section was payable did not stop with judgment and continued until payment.
40 In my judgment interest should continue to accrue after judgment at the rate of 8.25% provided payment is made to Mr Dumitrov before 30 June 2007. If payment is not made before then, the arithmetic mean of the 10-year Treasury Bond yields will need to be recalculated to include the rate as at 30 June 2007.
40 I direct the parties to bring in short minutes of order reflecting these additional reasons.
