Learning Objective 1 3-2

Product and Service Costing Financial Accounting Product costs are used to value inventory and to compute cost of goods sold. Managerial Accounting and Cost Management Product costs are used for planning, control, directing, and management decision making. 3-3

Learning Objective 2 3-4

Flow of Costs in Manufacturing Firm 3-5

Learning Objective 3 3-6

F Used for production of large, unique, high-cost items. F Built to order rather than mass produced. F Many costs can be directly traced to each job. F TWO TYPES: F Job-shop operations F Products manufactured in very low volumes or one at a time. F Batch-production operations F Multiple products in batches of relatively small quantity. Process Costing Job-Order Costing Types of Product-Costing Systems 3-7

F Typical job-order cost applications: v Special-order printing v Building construction F Also used in the service industry v Hospitals v Law firms Process Costing Job-Order Costing Types of Product-Costing Systems 3-8

Process Costing Job-Order Costing F Used for production of small, identical, low cost items. F Mass produced in automated continuous production process. F Costs cannot be directly traced to each unit of product. F Typical process cost applications: F Petrochemical refinery F Paint manufacturer F Paper mill Types of Product-Costing Systems 3-9

The primary document for tracking the costs associated with a given job is the job-cost record. Let’s investigate using the AFB Company Accumulating Costs in a Job-Order Costing System 3-10

Job-Order Cost Accounting 3-11

Let’s see one A materials requisition form is used to authorize the use of materials on a job. Job-Order Cost Accounting 3-12

Accumulate direct labor costs by means of a work record, such as a time ticket, for each employee. Let’s see one Job-Order Cost Accounting 3-15

Apply manufacturing overhead to jobs using a predetermined overhead rate based on direct labor hours (DLH). Let’s do it Job-Order Cost Accounting 3-18

Job-Order Cost Accounting 3-21

Learning Objective

Overhead is applied to jobs using a predetermined overhead rate (POHR) based on estimates made at the beginning of the accounting period. POHR = Budgeted manufacturing overhead cost Budgeted amount of cost driver (or activity base) Overhead applied = POHR × Actual activity Based on estimates, and determined before the period begins Actual amount of the allocation base, such as direct labor hours, incurred during the period Manufacturing Overhead Costs 3-23

Overhead is applied to jobs using a predetermined overhead rate (POHR) based on estimates made at the beginning of the accounting period. POHR = Budgeted manufacturing overhead cost Budgeted amount of cost driver (or activity base) Overhead applied = POHR × Actual activity Recall the Aluminum Boat example where: Overhead applied = $30 per DLH × 600 DLH = $18,000 Manufacturing Overhead Costs 3-24

Learning Objective

Let’s summarize the document flow we have been discussing in a job-order costing system. Job-Order Costing Document Flow Summary 3-26

Production Order for Job indirect material The materials requisition indicates the cost of direct material to charge to jobs and the cost of indirect material to charge to overhead. Material Requisition The production order for the job authorizes the start of the production process. Labor Time Records indirect labor Employee time tickets indicate the cost of direct labor to charge to jobs and the cost of indirect labor to charge to overhead. Actual Cost Driver (or Activity Base) X Predetermined Overhead Rate Apply Manufacturing Overhead Job-Order Costing Document Flow Summary 3-27

Let’s examine the cost flows in a job-order costing system. We will use T-accounts and start with materials. Job-Order System Cost Flows 3-28

Raw Materials Material Purchases Direct Material Mfg. Overhead Indirect Material Work in Process (Job-Cost Record) Job-Order System Cost Flows 3-29

Next let’s add labor costs and applied manufacturing overhead to the job-order cost flows. Are you with me? Job-Order System Cost Flows 3-30

Direct Labor Mfg. Overhead Indirect Material Direct Material Indirect Labor Direct Labor Indirect Labor Wages Payable Work in Process (Job-Cost Record) Job-Order System Cost Flows 3-31

Direct Labor Mfg. Overhead Indirect Material Direct Material Overhead Applied to Work in Process If actual and applied manufacturing overhead are not equal, a year-end adjustment is required. We will look at the procedure to accomplish this later. Indirect Labor Direct Labor Overhead Applied Indirect Labor Wages Payable Work in Process (Job-Cost Record) Job-Order System Cost Flows 3-32

Now let’s complete the goods and sell them. Still with me? Job-Order System Cost Flows 3-33

Cost of Goods Mfd. Finished Goods Cost of Goods Sold Cost of Goods Mfd. Cost of Goods Sold Direct Material Direct Labor Overhead Applied Work in Process (Job-Cost Record) Job-Order System Cost Flows 3-34

Let’s return to AFB Company and see what we will do if actual and applied overhead are not equal. Job-Order System Cost Flows 3-35

Actual Overhead costs for the year: $5,050,000 Actual direct labor hours worked for the year: 170,000 Applied Overhead = POHR × Actual Direct Labor Hours Applied Overhead = $30.00 per DLH × 170,000 DLH = $5,100,000 Applied overhead exceeds actual overhead by $50,000 This difference is called overapplied overhead. Overhead Application Example 3-36

Work in Process Finished Goods Cost of Goods Sold $50,000 may be allocated to these accounts. $50,000 may be closed directly to cost of goods sold. Cost of Goods Sold AFB Company’s Method OR Overapplied and Underapplied Manufacturing Overhead 3-37

Actual overhead costs $5,050,000 $50,000 overapplied Unadjusted Balance $50,000 Adjusted Balance Overhead Applied to jobs $5,100,000 AFB’s Mfg. Overhead for the year AFB’s Cost of Goods Sold for the year Overapplied and Underapplied Manufacturing Overhead 3-38

Learning Objective

Schedule of Cost of Goods Manufactured 3-41

Schedule of Cost of Goods Sold 3-42

Actual direct material and direct labor combined with actual overhead. Actual direct material and direct labor combined with predetermined overhead. Using a predetermined rate makes it possible to estimate total job costs sooner. Using a predetermined rate makes it possible to estimate total job costs sooner. Actual overhead for the period is not known until the end of the period. Actual overhead for the period is not known until the end of the period. Actual and Normal Costing 3-43
