Cost accounting data plays a key role in many management planning and control decisions. The division president will be able to make better operating and strategy decisions by being involved in key decisions about cost pools and cost allocation bases. Such an understanding, for example, can help the division president evaluate the profitability of different customers. 14-2 The salary of a plant security guard would be a direct cost when the cost object is the security department of the plant. It would be an indirect cost when the cost object is a product. 14-3 Exhibit 14-1 outlines four purposes for allocating costs: 1. To provide information for economic decisions. 2. To motivate managers and employees. 3. To justify costs or compute reimbursement. 4. To measure income and assets for reporting to external parties. 14-4 Exhibit 14-2 lists four criteria used to guide cost allocation decisions: 1. Cause and effect. 2. Benefits received. 3. Fairness or equity. 4. Ability to bear. The cause-and-effect criterion and the benefits-received criterion are the dominant criteria when the purpose of the allocation is related to the economic decision purpose or the motivation purpose. 14-5 Using the levels approach introduced in Chapter 7, the sales-volume variance is a Level 2 variance. By sequencing through Level 3 (sales-mix and sales-quantity variances) and then Level 4 (market-size and market-share variances), managers can gain insight into the causes of a specific sales-volume variance caused by changes in the mix and quantity of the products sold as well as changes in market size and market share. 14-6 The total sales-mix variance arises from differences in the budgeted contribution margin of the actual and budgeted sales mix. The composite unit concept enables the effect of individual product changes to be summarized in a single intuitive number by using weights based on the mix of individual units in the actual and budgeted mix of products sold. 14-7 A favorable sales-quantity variance arises because the actual units of all products sold exceed the budgeted units of all products sold. 14-8 The sales-quantity variance can be decomposed into (a) a market-size variance (because the actual total market size in units is different from the budgeted market size in units), and (b) a market share variance (because the actual market share of a company is different from the budgeted market share of a company). Both variances use the budgeted average contribution margin per unit. 14-1 14-9 Some companies who believe that reliable information on total market size is not available, choose not to compute market-size and market-share variances....
