[15] Further, Mr Wright's report supported the respondent's position that the mere fact that a certain number of hours are spent on particular tasks by a manager in the context of his operating a letting and managing business does not mean that the time costing of these hours should be automatically reflected in a manager's remuneration. This is because it was part of the management agreement that the appellant acquired rights under a letting agreement with the body corporate and lot holders in the building and, accordingly, obtained the opportunity to derive significant amounts of income from operating the letting business and providing other services to owners, tenants and their guests. Both the respondent and Mr Wright gave evidence that, as part of the exercise of assessing the fair market remuneration to be paid to a manager, the market recognizes the importance of maintaining a high standard of presentation and service which adds to the attractiveness of the property to prospective tenants and usually results in higher occupancy rates. This, in turn, leads to higher commission and service fees being payable to the manager. It follows, so it was said, that when the fair market remuneration is struck for a manager, the parties should take into account the opportunity of the manager to generate additional income from effort expended as manager. Mr Wright's evidence, therefore, demonstrates why a time and motion study of the manager's activities was not an appropriate basis on which to calculate his level of remuneration. The appellant is unable to point to any evidence that a person with the qualifications required by the service agreement would not have approached the valuation of the manager's remuneration in the same way as the respondent. It was the appellant who bore the onus of adducing such evidence.
