CHAPTER AN INTRODUCTION TO COST TERMS AND PURPOSES LEARNING OBJECTIVES Define and illustrate a cost object Distinguish between direct costs and indirect costs Explain variable costs and fixed costs Interpret unit costs cautiously Distinguish among manufacturing companies, merchandising companies, and service-sector companies Describe the three categories of inventories commonly found in manufacturing companies Differentiate between inventoriable costs and period costs Explain why product costs are computed in different ways for different purposes Present key features of cost accounting and cost management CHAPTER OVERVIEW Chapter provides concepts and terms, the tools for working with costs Two basic concepts are explained: (1) cost is a relative term and must be used in relationship to something, a cost object; and (2) common understanding of the terms and concepts facilitates communication Costs are critical information in most decisions Everything has a cost The critical need for accurate and reliable scorekeeping in which historical costs are properly identified and measured is underscored as decision support This chapter clearly defines the terms and concepts typically used in identifying costs As mentioned in Chapter 1, costs are ideally accumulated in a database (data warehouse or infobarn), measured and identified with various labels These data are assigned (“slice or dice”) to a specific cost object defined for a specific purpose Chapter uses “the product” of a manufacturing company as an example of cost accounting A good basic understanding of the terms and concepts introduced in this chapter are essential to an understanding of the concepts contained in this text The terms, relationships, and models developed in the remaining chapters are built upon the definitions and explanations in this chapter The classification of costs in Exhibit 2-10 is most useful CHAPTER OUTLINE Learning Objective 1: Define and illustrate a cost object I Costs and cost terminology—general TEACHING TIP: The use of jargon in the communication process can privilege a group of individuals who understand the meaning of the terms Jargon is used within families, companies, Greek fraternities and sororities, clubs, professional associations, etc Ask students to give examples of expressions or terms they use that carry special meaning to them within a particular group For example, a family may use the word “interesting” to mean “I not like the thing in question but I am not willing to say that to you.” One company uses the term “irate” to indicate a particularly troublesome customer The word carries special meaning to those who work within that department but the customer is unaware of being so branded The use of “menus” on company telephone systems is another way of branding callers—one must fit within a given category Cost concepts and terms are examples of jargon or branding that managers can learn to understand for being informed through the communication process A Use of cost concepts and terms to provide information Able to best use information if managers understand concepts and terms Facilitate communication among managers and management accountants if common understanding B Definition of term cost Resource sacrificed or forgone to achieve a specific objective Measurement, usually a monetary amount, that must be paid to acquire goods and services Use of term actual cost: cost incurred, historical, rather than budgeted or forecasted cost C Identification of cost object: anything for which a separate measurement of costs is needed/desired [Exhibit 2-1] D Stages of accounting for costs in a costing system Cost accumulation: collection of cost data in some organized means in an accounting system Cost assignment: designation of cost object to aid in decision making [Exhibit 2-2] a Tracing accumulated costs that have a direct relationship to a cost object Chapter An Introduction to Cost Terms and Purposes b Allocating accumulated costs that have an indirect relationship to a cost object Do multiple choice Assignment—see fixed/variable section II Costs and cost terminology—specific Learning Objective 2: Distinguish between direct costs and indirect costs A Assignment to a cost object: accuracy important for decision making Direct costs of a cost object: economically feasible to trace to cost object via cost tracing Indirect costs: related to cost object but not economically feasible to trace; assigned via cost allocation Factors affecting direct/indirect classification a Materiality of the cost in question b Available information-gathering technology c Design of operations d Choice of cost object: generally the broader the definition of the cost object, the higher the proportion of total costs that are direct costs and more confidence in cost accuracy Do multiple choice Assign Exercise 2-17 Learning Objective 3: Explain variable costs and fixed costs B Behavior pattern in relation to changes in the related level of total activity or volume Costing systems: record cost of resources acquired and track how then used Basic types of cost-behavior with respect to a specific cost object and given time period a Variable [Exhibit 2-3] i Changes in total in proportion to changes in the related level of total activity Chapter An Introduction to Cost Terms and Purposes ii Use as per unit for estimates of total costs b Fixed [Surveys of Company Practice] i Unchanged in total for a given time period despite wide changes in related level of total activity ii Always focus on total costs when making cost estimates for fixed costs Individual costs not inherently variable or fixed but dependent upon related activity Choice of cost driver: a variable with cause-and-effect relationship between change in level of activity and change in level of total costs [Concepts in Action] Consideration of relevant range: band of normal activity level with specific relationship between level of activity and particular cost amount [Exhibits 2-4 and 2-5] Do multiple choice Assign Exercises 2-22 and 2-23 with special emphasis on identification of the cost object Learning Objective 4: Interpret unit costs cautiously C Total costs and unit costs Generally total cost amounts should be used in decision making Some decisions need unit costs (average costs) but should be used cautiously Do multiple choice Assign Exercises 2-24 and 2-25 III Accounting for the cost of a product Learning Objective 5: Distinguish among manufacturing companies, merchandising companies, and service-sector companies A Product defined in three types of companies [Exhibit 2-6] Manufacturing-sector companies: convert materials and components into finished good Merchandising-sector companies: purchase product and sell without changing basic form Service-sector companies: provide services or intangible products Chapter An Introduction to Cost Terms and Purposes Do multiple choice Assign Exercises 2-18, 2-19, 2-20, and 2-27 Learning Objective 6: Describe the three categories of inventories commonly found in manufacturing companies B Product inventories for manufactured goods: stages in the conversion process Direct materials: direct materials in stock and awaiting use in the manufacturing process Work in process: goods partially worked on but not yet fully completed Finished goods: goods fully completed but not yet sold C Product as cost object: classifications of manufacturing costs Direct materials costs Direct manufacturing labor costs Indirect manufacturing costs, manufacturing overhead costs or factory overhead costs Do multiple choice Assign Exercises 2-28, 2-29 and 2-30, 2-36 and 2-37 Learning Objective 7: Differentiate between inventoriable costs and period costs D Product costs for financial statement placement [Exhibit 2-8] Inventoriable costs: all costs of a product that are regarded as an asset (balance sheet) when incurred and then become cost of goods sold (income statement) when product sold a Manufacturing company: all manufacturing costs are inventoriable costs b Merchandising company: costs of purchasing goods resold in their same form c Service company: no inventoriable costs because no inventories of product Period costs: all costs in the income statement other than cost of goods sold Do multiple choice and Assign Exercise 2-26 E Product cost reported: Schedule of cost of goods manufactured and sold [Exhibit 2-6] Three categories of manufacturing costs = “manufacturing costs incurred during period ” Chapter An Introduction to Cost Terms and Purposes a Direct materials – both as inventory and manufacturing cost b Direct manufacturing labor costs c Indirect manufacturing costs Three categories of manufacturing inventories—stages of the conversion process a Direct materials – used to calculate direct materials used at beginning of schedule b Work in process c Finished-goods [Exhibit 2-7] F Other terminology for product costs Prime costs: all direct manufacturing costs Conversion costs: all manufacturing costs other than direct material costs IV Judgment factors A Differences in way costs can be defined and classified [Exhibit 2-10] Careful to define and understand way costs are measured in a company or situation Illustrate by manufacturing labor costs a Detailed classification to enhance cause-effect relationship to extent possible b Detailed classification agreed upon to promote company-wide communication c Detailed classification for clarity to preclude disputes B Differences in uses of product cost: sum of costs assigned to a product for a specific purpose Learning Objective 8: Explain why product costs are computed in different ways for different purposes Product cost for purpose of pricing and product-mix emphasis [Exhibit 2-9] Product cost for purpose of contracting with government agencies Product cost for purpose of preparing financial statements for external reporting under GAAP Chapter An Introduction to Cost Terms and Purposes Do multiple choice Assign Exercise 2-33 Learning Objective 9:

In their book, Sorting Things Out: Classification and Its Consequences, Geoffrey Bowker and Susan Star describe the constant activity of labeling and sorting of all that we have and in life They note that not all classifying is formal or even noticed by us For those formal classification systems we can usually find some gaps in the system and are unable to assign everything to a specific category The example is given of disease classifications for medical records We not have perfect knowledge of all diseases and the interaction of various ailments— yet a category must be picked Shakespeare’s “What’s in a name: That which we call a rose by any other name would smell as sweet” (Romeo and Juliet) may not be so poetic when something or someone is mistakenly assigned to what is perceived as an undesirable category (student grades, for example) In studying the classification of costs, consideration should be given to such problems as imperfect knowledge, inaccurate description, and simplistic classification systems These not negate the usefulness of the present classification system but can be used to inform it, especially when critical decisions are being made on the basis of that present system Bowker, George & Star, Susan 1999 Sorting Things Out: Classification and Its Consequences Cambridge MA: MIT Press 10 Chapter An Introduction to Cost Terms and Purposes 10 Explain variable costs and fixed costs How can a cost driver/cost relationship be developed? The development of a relationship is similar to that of developing a working model (often labeled the “scientific method”) Thoughtful observation is primary As one observes recorded data, both financial and nonfinancial, noting relevant changes in related factors, causal relationships can be inferred From the inferences, assessment can be made about the plausibility of such a cause-effect relationship Most relationships are complex and all of the interrelationships cannot be discerned, therefore a model cannot be as accurate and reliable as the actual relationship Models must be simplistic in order to be useful (costbenefit approach) They must also be updated from time to time or cast off for a new approach as things change Models can be relied upon to eliminate some errors that could occur without their use If a model is used like a “checklist” then inexperienced workers can be productive more quickly by following an “experience model” before they gain complete understanding Artificial intelligence is based upon human models of thinking about a particular task In the example of filling out income tax returns, the “model” gave right answers more often than the professionals did because the professionals sometimes forget to include a minor item or consideration Interpret unit costs cautiously Explain why a variable cost stays the same per unit and a fixed cost changes per unit Which cost would decision makers prefer to use as a per unit cost and why? In calculating a per unit cost, division is used Variable costs derive the name variable from their total cost behavior As the numerator changes (the cost), the denominator (the cost driver) also changes in proportion so that the quotient is the same at any level within the relevant range A fixed cost, however, means that the numerator is fixed in total within the relevant range As the denominator changes, the numerator does not, and the resulting quotient changes with each change in the denominator The name of the cost is based upon total cost behavior and does not apply to per unit cost behavior, but in fact, the unit behavior can be described as the opposite of how the total behavior is described Most decision makers would well to use only variable costs on a per unit basis Decisions are about the future, and in predicting costs, one would want to use a cost for which the behavior was more easily predictable Fixed costs can be predicted more accurately in total To use them as unit costs, one would have to carefully predict a level of activity for the cost driver If another activity level were to be considered, the per unit cost would have to be recalculated; whereas for the variable cost, several levels of activity could be used without recalculating the per unit cost (relevant range concept) Distinguish among manufacturing companies, merchandising companies, and service-sector companies Why would a service-sector company need cost accounting when it does not have product inventories or cost of goods sold? Service-sector companies have products and need to know if the revenues generated by those “products” or services exceed the cost of furnishing the service For financial accounting the service cannot be inventoried because it does not exist until it is performed, at which time it becomes an expense The expense is not labeled “cost of goods sold” because it is not a “good” in the traditional meaning Cost accounting is more than costing a product that can be inventoried Costs must be 11 Chapter An Introduction to Cost Terms and Purposes 11 accumulated and assigned for service-sector companies The greater context of cost management is also important for service-sector companies Describe the three categories of inventories commonly found in manufacturing companies What effect, if any, does having a two-part classification of manufacturing costs (Direct materials and Manufacturing overhead) rather than a three-part classification of manufacturing costs (Direct materials, Direct manufacturing labor, and Manufacturing overhead) have on the categories of inventories commonly found in manufacturing companies? Could classifications of manufacturing costs be changed such as to affect the inventory categories? In general, the number of classifications of manufacturing costs does not affect the categories of inventories The amount of the cost may be somewhat changed in that a more detailed classification could result in more accurate costing, though be more expensive to maintain The specific change of a three-part to a two-part classification system as noted in the text does no more than reclassify the labor cost from direct to indirect If labor constitutes less cost due to changes in the manufacturing process, a change from a three-part to a two-part is clearly justified Changes resulting from just-in-time or throughput costing may indeed change the inventory categories by eliminating the work in process category, for example With just-in-time costing, a two-part classification of costs may be used The two-part classification could be “raw and in-process” and “finished goods” necessitating only those two inventories rather than the typical three Differentiate between inventoriable costs and period costs Using the value chain concept of business functions explain why costs preceding the function of production are not considered inventoriable costs for external financial statements The definition of an asset, of which inventory is one, is the right to future benefit A product that can be sold for more than it cost promises future benefit, thus inventory is classified as an asset The cost of research and development as well as design may indeed impart future benefit, but such benefit is difficult to measure Generally accepted accounting principles would expense those costs rather than capitalize them (classified as assets) Explain why product costs are computed in different ways for different purposes If costs can be assigned in different ways for different purposes, how does one know what costs to combine? The purpose for which costs are to be developed must be clearly defined From that clear purpose, a cost object can be identified so costs can then be appropriately assigned In the situations in which the cost object may be defined commonly as the “product cost” but for which differing amounts of the same costs are assigned, one can look more closely at the particular purposes The cost object, though appearing to be the same “product” in various situations, is not For purposes of pricing, the “product” must cover all costs of the organization for that is the means by which the company would earn a profit For purposes of costing the “product” for a specific contract, the terms of the contract would have to be met For financial accounting purposes, the cost of the “product” would have to meet the definition given under GAAP Using a common label for a cost object such as “product cost” is not enough to define the combining of cost but one must look to the particular purpose and its full meaning 12 Chapter An Introduction to Cost Terms and Purposes 12 Present key features of cost accounting and cost management What is the reason for incurring costs?
