A. Expenses in connection with issue of equity shares
B. Preoperative expenses
C. Heavy advertising expenses to introduce a new product
D. Legal expenses incurred in defending a suit for breach of contract to supply goods

D. Deferred revenue expenditure is a revenue expenditure whose benefit lasts for more than one accounting periods and is therefore written off during the periods over which the benefit lasts(However, AS 26 requires that Deferred revenue expenditure is expenses wholly in the year of incurrence). Legal expenses incurred in defending a suit for breach of contract for supply of goods does not satisfy the prerequisites of a deferred revenue expenditure.
