Changes in the transaction price
87 After contract inception, the transaction price can change for various reasons,
including the resolution of uncertain events or other changes in circumstances
that change the amount of consideration to which an entity expects to be
entitled in exchange for the promised goods or services.
88 An entity shall allocate to the performance obligations in the contract any
subsequent changes in the transaction price on the same basis as at contract
inception. Consequently, an entity shall not reallocate the transaction price to
reflect changes in stand-alone selling prices after contract inception. Amounts
allocated to a satisfied performance obligation shall be recognised as revenue, or
as a reduction of revenue, in the period in which the transaction price changes.
