MANAGEMENT ACCOUNTING (VOLUME I) - Solutions ManualCHAPTER COST CONCEPTS AND CLASSIFICATIONS I Questions The phrase “different costs for different purposes” refers to the fact that the word “cost” can have different meanings depending on the context in which it is used Cost data that are classified and recorded in a particular way for one purpose may be inappropriate for another use Fixed costs remain constant in total across changes in activity, whereas variable costs change in proportion to the level of activity Examples of direct costs of the food and beverage department in a hotel include the money spent on the food and beverages served, the wages of table service personnel, and the costs of entertainment in the dining room and lounge Examples of indirect costs of the food and beverage department include allocations of the costs of advertising for the entire hotel, of the costs of the grounds and maintenance department, and of the hotel general manager’s salary The cost of idle time is treated as manufacturing overhead because it is a normal cost of the manufacturing operation that should be spread out among all of the manufactured products The alternative to this treatment would be to charge the cost of idle time to a particular job that happens to be in process when the idle time occurs Idle time often results from a random event, such as a power outage Charging the cost of the idle time resulting from such a random event to only the job that happened to be in process at the time would overstate the cost of that job a Uncontrollable cost b Controllable cost c Uncontrollable cost Product costs are costs that are associated with manufactured goods until the time period during which the products are sold, when the product costs become expenses Period costs are expensed during the time period in which they are incurred 8-1 Chapter Cost Concepts and Classifications The most important difference between a manufacturing firm and a service industry firm, with regard to the classification of costs, is that the goods produced by a manufacturing firm are inventoried, whereas the services produced by a service industry firm are consumed as they are produced Thus, the costs incurred in manufacturing products are treated as product costs until the period during which the goods are sold Most of the costs incurred in a service industry firm to produce services are operating expenses that are treated as period costs Product costs are also called inventoriable costs because they are assigned to manufactured goods that are inventoried until a later period, when the products are sold The product costs remain in the finished goods inventory account until the time period when the goods are sold A sunk cost is a cost that was incurred in the past and cannot be altered by any current or future decision A differential cost is the difference in a cost item under two decision alternatives 10 a b c d Direct cost Direct cost Indirect cost Indirect cost 11 The two properties of a relevant cost are: it differs between the decision options it will be incurred in the future 12 The three types of product costs are: direct materials – the materials used in manufacturing the product, which become a physical part of the finished product direct labor – the labor used in manufacturing the product factory overhead – the indirect costs for materials, labor, and facilities used to support the manufacturing process, but not used directly in manufacturing the product 13 The three types of manufacturing inventories are: materials inventory – the store of materials used in the manufacturing process or in providing the service 8-2 Cost Concepts and Classifications Chapter work in process inventory – accounts for all costs put into the manufacturing of products that are started but not complete at the financial statement date finished goods inventory – the cost of goods that are ready for sale 14 Direct materials include the materials in the product and a reasonable allowance for scrap and defective units, while indirect materials are materials used in manufacturing that are not physically part of the finished product II Exercises Exercise (Schedule of Cost of Goods Manufactured and Sold;
