It is company policy to hire all plant and machinery required for the implementation of all orders obtained, rather than to purchase its own plant and machinery. Windhoek Renovations will enter into an advance hire agreement contract for the coming year at one of the three levels – high, medium, or low, which correspond to the requirements of a high, medium, or low level of orders obtained. The level of orders obtained will not be known when the advance hire agreement contract is entered into. A set of probabilities have been estimated by management as to the likelihood of the orders being high, medium, or lower level. Where the advance hire agreement entered is lower than that required for the level of orders obtained, a premium rate must be paid to obtain additional plant and machinery required. No refund is obtainable where the advance hire agreement for plant and machinery is at a level more than that required to satisfy the site clearance and preparation orders obtained.
