7 A contract with a customer may be partially within the scope of this Standard and partially within the scope of other Standards listed in paragraph 5.
(a) If the other Standards specify how to separate and/or initially measure one or more parts of the contract, then an entity shall first apply the separation and/or measurement requirements in those Standards. An entity shall exclude from the transaction price the amount of the part (or parts) of the contract that are initially measured in accordance with other Standards and shall apply paragraphs 73–86 to allocate the amount of the transaction price that remains (if any) to each performance obligation within the scope of this Standard and to any other parts of the contract identified by paragraph 7(b).
(b) If the other Standards do not specify how to separate and/or initially measure one or more parts of the contract, then the entity shall apply this Standard to separate and/or initially measure the part (or parts) of the contract.
