A customer receives a discount for purchasing a bundle of goods or services if
the sum of the stand-alone selling prices of those promised goods or services in
the contract exceeds the promised consideration in a contract. Except when an
entity has observable evidence in accordance with paragraph 82 that the entire
discount relates to only one or more, but not all, performance obligations in a
contract, the entity shall allocate a discount proportionately to all performance
obligations in the contract. The proportionate allocation of the discount in
those circumstances is a consequence of the entity allocating the transaction
price to each performance obligation on the basis of the relative stand-alone
selling prices of the underlying distinct goods or services.
