If in any year ended 30 June the Determined Rate is less than five (5) per centum per annum the Company and the Affiliated Companies between them shall pay to the Fund as soon as convenient after the close of that year the amount necessary to increase that rate to five (5) per centum per annum in respect of those persons who were Members on 30 June 1992.
"Determined Rate" means an annual rate of interest determined in accordance with any applicable requirement of the Relevant Law as follows -
(a) four and one-half per centum (4½%) per annum in each financial year to 30 June 1986 and in the period 1 July 1986 to 31 March 1987;
(b) following 30 June 1987, a rate declared by the Trustees on the advice of an Actuary appointed by them to apply to the period 1 April 1987 to 30 June 1987, having regard to the investment earnings of the Fund during that period;
(c) following each subsequent 30 June, a rate declared by the Trustees on the advice of an Actuary appointed by them to apply to the financial year ending on that 30 June, having regard to the investment earnings of the Fund during that financial year PROVIDED THAT in respect of persons who were Members on 30 June 1992 the Determined Rate shall not be less than 5%
(d) for the purposes of calculating benefits under this Deed, an interim rate determined by the Trustees on the advice of an Actuary appointed by them to apply from the end of the most recent period in respect of which a rate has been declared under (b) or (c) above, having regard to the best estimate of the investment earnings of the Fund since the end of that period.
8 From 30 March 2001 the management of the Fund was transferred, by way of agreement, to William M Mercer Pty Ltd. From that date, the rate of Mr Taylor's superannuation investment return was guaranteed by clause 2.5 of the Participation Agreement between Mercer Retirement Trust and Metal Manufacturers Limited:
2.5 MINIMUM EARNING RATE
2.5.1 The investment earning credited to the Member Account of an Eligible Previous Fund Member for a financial year may not be less that 5% of the member Account Balance of that Member on the last day of the financial year excluding investment earnings that would otherwise be allocated (by whatever means) for that period and taking into account the timing of payments and receipts during this year.
2.5.2 If the effect of clause 2.5.1 is to require an additional payment to be made to the Member Account of an Eligible Previous Fund Member that is not otherwise available to be met out of investment earnings for that Member, the Trustee shall advise that Member's Employer of the amount required for payment.
9 We state at the outset that this case turns on very particular circumstances. As the Full Bench noted in Austeck, the question of whether an applicant's annual remuneration exceeds the prescribed amount is essentially a question of fact to be determined according to the circumstances of each case and having regard to the purpose of s83(1)(b). When Mr Taylor's employment was terminated, there were only fourteen "Eligible Previous Fund Members" to whom clause 2.5 applied. Mr Shan Murphy of Mercer Human Resource Consulting Pty Ltd (a corporate authorised representative of Mercer Investment Nominees Limited) advised the respondent's financial controller, Mr Chris Tobin, that in his experience the guaranteed interest rate was unique: he was not aware of any other plan in the Mercer Super Trust with a similar feature. We note that the most common type of superannuation funds are accumulated contributions funds. But for the issues relating to the application of Austeck, leave may well have been refused.
10 It may be seen from the clauses extracted above that in years where the superannuation fund earnings are 5 per cent or greater than 5 per cent, no employer "top up" is required and this was the case it would seem from 1992 to 2001. Although the characterisation of such payments as "top-ups" is, to an extent, misleading (it was really an adjustment where the investment return was insufficient, depending upon how the Fund operated in practice) we will use the expression as it was used throughout this matter by both parties.
11 Conversely, in years where the fund does not perform and the annual return is less than 5 per cent, as it was in the financial years ending 2002 and 2003, the employer upon advice from the trustee as to the amount, is required to make up the shortfall by means of the so-called "top up" payment. In the financial year ended 2002, the fund returned negative earnings of 3.1 per cent and the "top up" payment to Mr Taylor's account was $30048.71. In the financial year ended 2003 the fund again returned negative earnings, this time 0.7 per cent and the "top up" payment (made in July 2003) was $22320.91. However, Mr Taylor's employment was terminated in the financial year ending 2004. When Mr Taylor received his superannuation payment upon termination, no "top up" was required, or made under the Deed or his contract of employment. It is the payment relating to the financial year ended 2003 that is central to the controversy here.
12 If that amount is included in the calculation of Mr Taylor's annual remuneration, then the annual remuneration is greater than the amount of $85400 relevantly prescribed by the Industrial Relations (General) Regulation 2001 for the purposes of s83(1)(b) of the Industrial Relations Act 1996 and Mr Taylor being award-free is exempted from the unfair dismissal jurisdiction.
CONSIDERATION
13 We shall discuss the following two issues in turn: whether the "top-up" payment of $22,320.91 should be included in the calculation of Mr Taylor's "annual remuneration"; and, more generally, whether such payments in this case could properly be described as "remuneration" within the meaning of s 83(1)(b) of the Act.
14 The Full Bench in Austeck considered the following question (in the context of the annual salary of the applicant in that case):
"in determining an employee's annual remuneration, should it be done on the basis of actual remuneration earned by the employee in the 12 months preceding termination of the employment" [41]
15 In determining that question the Full Bench in Austeck said at [45]:-
We consider that a reference to "annual remuneration", in the literal sense of that expression, is at odds with an interpretation that favours looking at what the applicant earned in the 12 months preceding termination of employment. We consider that the expression " annual remuneration" should be construed as the rate of remuneration fixed by the contract of employment at the point of termination. The word 'annual', in the context in which it appears, conditions the word remuneration so that the expression 'annual remuneration' is given the meaning - the rate actually fixed as the contractual yearly remuneration.
