Learning Objective 3 Indirect costs cannot be identified specifically and exclusively With a given cost objective in an economically feasible way. Unallocated costs are recorded but not assigned to any cost object.

A cost-allocation base is some measure of input or output that determines the amount of cost to be allocated to a particular cost object. An ideal cost-allocation base would measure how much of the particular cost is caused by the cost objective. Note the similarity of this definition to that of a cost driver—an output measure that causes costs. Therefore, most allocation bases are cost drivers. Learning Objective 4

Four purposes of cost allocation:  Predict the economic effects of strategic and operational control decisions.  Provide desired motivation and to give feedback for performance evaluation.  Compute income and asset valuations for financial reporting.  Justify costs or obtain reimbursement.

Activity-Based Management A value-added cost is the cost of an activity that cannot be eliminated without affecting a product’s value to the customer. In contrast, nonvalue-added costs are costs that can be eliminated without affecting a product’s value to the customer. Learning Objective 8
