13 Accepting for the purpose of analysis the above figures, the amount remaining of $63,000 is attributable to loss of permanent employment. The claim of the respondent was based upon a net income of $372 per week, projected to age 65. No claim was made on the basis of promotion or anticipated higher remuneration. The formula, discounted, produces a figure of $212,747. The respondent's contribution to a benefit fund amounted to $32.50 per week which, discounted and projected to age 65, results in the amount of $18,587. Thus the notional award of between $60,000 and $65,000 must be compared with a maximum claim of $231,000, a percentage figure of between 26 per cent and 28 per cent. This calculation does not take into account the employer's contribution to superannuation or the provision of a meal, the effect of which would be to lessen the percentage figure since the notional income would be higher. This differs from the percentage figures advanced on behalf of the appellant. An alternate basis for examination would be to consider the amount assessed of $90,000 in terms of 20 years' loss of income which would equate with a figure of $160.87 per week, which in turn represents a percentage figure of 43 per cent of the actual anticipated salary. This sum was reduced for contingency by a further 15 per cent, making the actual award, in percentage terms, far less. The respondent might not agree with the conclusion and might challenge probability (Malec v J C Hutton Proprietary Limited (supra)), but the reasoning process is susceptible to examination and challenge. The conclusion is not such as to preclude a basis for review.
