(a) Deferred Revenue Expenditure is an expenditure which is revenue in nature and incurred during an accounting period. These expenses are large in amount and the benefits are not consumed within the same accounting period. Suppose that a company is introducing a new product to the market and decides to spend a large amount on its advertising in the current accounting period. This marketing spend is supposed to draw benefits beyond the current accounting period. 

(b) Semi-variable costs are costs or expenses whose behaviour is partially fixed and partially variable. Semi-variable costs remain fixed up to a particular production volume. Beyond this volume, semi-variable costs increase in direct proportion to output. Wages, for instance, are semi-variable costs which multiply by 1.5 beyond 40 hours worked in a given week. 

(c) Warehouses play an important role in the process of price stabilization. They help in the stabilization of prices by adjusting demand and supply. Scarcity in supply of goods may increase their price in the market. Again, excess production and supply may also lead to fall in prices of the product. By maintaining a balance of supply of goods, warehousing leads to price stabilization.

(d) Master budget works as a summary budget for the overview of the business owners and the management. The master budget indicates how much the organization is earning and what the expenses are incurred as a whole. 

(e) Logistics is used more broadly to refer to the process of coordinating and moving resources – people, materials, inventory and equipment – from one location to storage at the desired destination.
