MANAGEMENT ACCOUNTING (VOLUME I) - Solutions ManualCHAPTER12 VARIABLE COSTING I Questions The variable costing technique does not consider fixed costs as unimportant or irrelevant, but it maintains that the distinction between behaviors of different costs is crucial for certain decisions The central issue in variable costing is what is the proper timing for release of fixed manufacturing overhead as expense: at the time of incurrence, or at the time the finished units to which the fixed overhead relates are sold Direct costing would be more accurately called variable or marginal costing because in substance it is the inventory costing method which applies only variable production costs to product; fixed factory overhead is not assigned to product Marketing and administrative costs are treated as period costs under both variable costing and absorption costing methods of product costing Under absorption costing, as a company manufactures units of product, the fixed manufacturing overhead costs of the period are added to the units, along with direct materials, direct labor, and variable manufacturing overhead If some of these units are not sold by the end of the period, then they are carried into the next period as inventory The fixed manufacturing overhead cost attached to the units in ending inventory follow the units into the next period as part of their inventory cost When the units carried over as inventory are finally sold, the fixed manufacturing overhead cost that has been carried over with the units is included as part of that period’s cost of goods sold Many accountants and managers believe absorption costing does a better job of matching costs with revenues than variable costing They argue that all manufacturing costs must be assigned to products to properly match the costs of producing units of product with the revenues from the units when they are sold They believe that the fixed costs of depreciation, taxes, insurance, supervisory salaries, and so on, are just as essential to manufacturing products as are the variable costs 12-1 Chapter12 Variable Costing If fixed manufacturing overhead cost is released from inventory, then inventory levels must have decreased and therefore production must have been less than sales Under absorption costing it is possible to increase net operating income without increasing sales by increasing the level of production If production exceeds sales, units of product are added to inventory These units carry a portion of the current period’s fixed manufacturing overhead costs into the inventory account, thereby reducing the current period’s reported expenses and causing net operating income to rise Generally speaking, variable costing cannot be used externally for financial reporting purposes nor can it be used for tax purposes 10 If production exceeds sales, absorption costing will show higher net operating income than variable costing The reason is that inventories will increase and therefore part of the fixed manufacturing overhead cost of the current period will be deferred in inventory to the next period under absorption costing By contrast, all of the fixed manufacturing overhead cost of the current period will be charged immediately against revenues as a period cost under variable costing II Exercises Exercise (Variable and Absorption Costing Unit

P(20,000) Requirement Production went up sharply in Year thereby reducing the unit product cost, as shown in (2a) This reduction in cost, combined with the large amount of fixed manufacturing overhead cost deferred in inventory for the year, more than offset the loss of revenue The net result is that the company’s net operating income rose even though sales were down Requirement The fixed manufacturing overhead cost deferred in inventory from Year was charged against Year operations, as shown in the reconciliation in (2b) This added charge against Year operations was offset somewhat by the fact that part of Year 3’s fixed manufacturing overhead costs was deferred in inventory to future years [again see (2b)] Overall, the added costs charged against Year were greater than the costs deferred to future years, so the company reported less income for the year even though the same number of units was sold as in Year Requirement a Several things would have been different if the company had been using JIT inventory methods First, in each year production would have been geared to sales so that little or no inventory of finished goods would have been built up in either Year or Year Second, unit product costs probably would have been the same in all three years, since these costs would have been established on the basis of expected sales (50,000 units) for each year Third, since only 40,000 units were sold in Year 2, the company would have produced only that number of units and therefore would have had some underapplied overhead cost for the year (See the discussion on underapplied overhead in the following paragraph.) b If JIT had been in use, the net operating income under absorption costing would have been the same as under variable costing in all three years The reason is that with production geared to sales, there would have been no ending inventory on hand, and therefore there would have been no fixed manufacturing overhead costs deferred in inventory to 12-11 Chapter12 Variable Costing other years Assuming that the company expected to sell 50,000 units in each year and that unit product costs were set on the basis of that level of expected activity, the income statements under absorption costing would have appeared as follows: Sales Less cost of goods sold: Cost of goods manufactured @ P16 per unit Add underapplied overhead Cost of goods sold
