Revenue is usually recognized at the point of sale (a point in time). Under special circumstances, however, bases other than the point of sale are used for the timing of revenue recognition.

(a) Why is the point of sale usually used as the basis for the timing of revenue recognition?

(b) the special circumstances when bases other than the point of sale are used, discuss the advantages of each of the following objections to the point-of-sale basis of revenue recognition:

(i) It is too conservative because revenue is earned throughout the entire process of production.

(ii) It is not conservative enough because accounts receivable do not represent disposable funds, sales returns and allowances may be made, and collection and bad debt expenses may be incurred in a later period.
