An entity shall recognise the following costs as expenses when incurred:
(a) general and administrative costs (unless those costs are explicitly
chargeable to the customer under the contract, in which case an entity
shall evaluate those costs in accordance with paragraph 97);
(b) costs of wasted materials, labour or other resources to fulfil the contract
that were not reflected in the price of the contract;
(c) costs that relate to satisfied performance obligations (or partially
satisfied performance obligations) in the contract (ie costs that relate to
past performance); and
(d) costs for which an entity cannot distinguish whether the costs relate to
unsatisfied performance obligations or to satisfied performance
obligations (or partially satisfied performance obligations).
