Chapter 3 Flashcards
Cost Objects
Resources or activities that serve as the basis for management decisions
Require separate cost measurements and may be different products, product lines, departments, geographic territories etch
Single cost object can have more than one measurement
Common Cost Objects
- Product Costs
- Period Costs
- Manufacturing Costs
- Nonmanufacturing Costs
Goal of measuring cost objectives include:
- Product costing (inventory and COG manufactured and sold)
- Income determination (Profitability)
- Efficiency Measurements (comparisons to standards)
Product Costs
All cost related to the manufacturing of a product
Are inventoriable
Attach to the unit of output
Inventory, COG Manufactured, and Sold
Components: direct materials, direct labor and manufacturing overhead applied
Period Costs
Expensed in the period in which they are incurred and are not inventoriable
Include selling, general, and administrative expenses as well as interest (financing expense)
Cost of selling product and administering and managing the operation of the firm
Manufacturing Cost
Treated as Product Costs
Including all costs associated with the manufacture of a product
Manufacturing costs are specifically capitalized to the cost of the manufactured product
Consist of both direct and indirect costs
Nonmanufacturing Costs
Treated as Period Costs
Costs that do not related to the manufacture of a product
Selling, General, and administrative expenses
Direct Costs
Can be easily traced to the cost pool or object
Common Examples:
Direct Raw Materials
Direct Labor
Indirect Costs
No easily traceable to a cost pool or object
Typically benefit two or more cost pools or object
Common Examples:
Indirect Materials
Indirect Labor
Other Indirect Costs
Prime Cost
= Direct Labor + Direct Material
Conversion Cost
= Direct Labor + Manufacturing Overhead
Can be used when a customer furnishes the material used in manufacturing a product
Overhead Allocation Using Cost Drivers
- Allocation Bases: cost drivers used to allocate indirect costs
- Accounting for Overhead: When traditional costing is used, all indirect costs are allocated to a single cost pool (or account) called “overhead”
Allocation Using Traditional Costing
Step 1: Overhead Rate = Budgeted Overhead Costs / Estimated Cost Driver
Step 2: Actual Cost Driver * Overhead Rate
Variable Cost
Behavior: changes proportionately with the cost driver
Amount: Constant per Unit, Total Varies
Long-Run Charatertiscs: short and long run effects are the same within relevant ranges
Fixed Costs
Behavior: in short-term and within relevant ranges, fix costs do not change
Amount: Varies per Unit, Total Remains the Same
Long-run characteristics: given enough time, any cost can be considered variable
Semi-Variable Costs (Mixed)
Costs that include components that remain constant over the relevant range and include components that fluctuate in direct relation to production
Relevant Range
Range for which assumptions of the cost driver (linear relationship with the cost incurred) are valid
Cost Behaviors
Cost Accumulation System
Used to assign costs to products
System used is driven by the cost object involved
Most Common = job-order costing and process costing
Others: Operations costing (uses both job and process costing), Backflush Costing, and Life Cycle Costing
Costs of Good Manufactured
Statement that accounts for the manufacturing costs of the products completed during the period
Costs = direct material, direct labor, and manufacturing overhead
COGM = COGS + Ending Finished Goods Inventory - Beginning Finished Goods Inventory
= Total Manufacturing Cost + Beginning WIP - Ending WIP
Where Total Manufacturing Costs = Direct Materials Used + Direct Labor + Applied OH
Where Direct Materials Used = Beginning Inventory of Direct Materials + Purchases - Purchase Returns/ Allowance + Transport In - Ending Inventory of Direct Materials
Manufacturing costs incurred during the period are increased or decreased by the net change in work-in-process inventory (beginning WIP minus ending WIP) to equal cost of good manufactured
Cost of Good Sold
statement for a manufacturer is very similar to one prepared for a retailer expect that cost of goods manufactured is used in place of purchases made during period
WIP Inventory Beginning + Cost of Good Manufactured = Costs of Goods Available for Sale - Finished Goods Inventory Ending = COGS
COGS = COGM + Beginning Finished Goods Inventory - Ending Finished Goods Inventory
Job Order Costing
Identifies the job or individual units or batches as the cost objective and is used when relatively few units are produced and when each unit is UNIQUE or easily identifiable
Cost is allocated to a specific job as it moves through the manufacturing process
Job-Cost Records are maintained for each product, service or batch of products and they serve as the primary record used to accumulate all costs for the job
Internal Documents Use: Materials Requisitions, Labor Time Tickets, Job-Order Costing
Process Costing
Averages costs and applies them to a larger number of homogeneous items
Steps:
- Summarize the flow of physical units (beginning with the production report)
- Calculate “equivalent unit” output
- Accumulate the total costs to be accounted for (production report)
- Calculate the average unit costs based on total costs and equivalent units
- Apply the average costs to the units completed and the units remaining in the ending work-in-process inventory
Equivalent Units
Costs must be attached to the completed units as well as to the units that are partially completed at the end of each period
Defined: equivalent unit of direct material, direct labor, or conversion costs is equal to the amount of direct material, direct labor or conversion costs necessary to complete one unit of productions
Process Costing Assumptions
- Transfers in are 100% Complete
- Timing of Addition of Direct Material
- Addition at Beginning or During a Process: can be 100% complete or partially complete
- Addition at the End of a Process
- Any material added at the very end of a process will not be in the work-in-process inventory at the month end
Calculating Using FIFO
Ending inventory is priced at the cost of manufacturing during the period, assuming that beginning inventory was completed during the period
Equivalent Unit Components
- Completion of units on hand at the beginning of the period
- Units started and completed during the period (Units Completed - Beginning WIP)
- Units Partially Complete at the End of the Period
Cost Components:
Current Costs incurred during the period are allocated to the equivalent units produced during the period
Formula:
Beginning WIP * % to be Completed XXX
Units Completed - Beginning WIP + XXX
Ending WIP * % Completed + XXX
Equivalent Units XXX
Cost Per Equivalent Units:
= Current Cost Only
Equivalent Units
Calculating Using Weighted Average
Averages the cost of production during the period with the costs in the beginning work-in-process inventory
Equivalent Unit Components:
- Units completed during the month (Beginning WIP + Units stated and completed during the month)
- Units partially complete at the end of the period
Total cost, including both the costs of beginning inventory and current costs, are allocated to equivalent units to arrive at a weighted average unit cost
Formula:
Units Completed XXX
Ending WIP * % Completed +XXX
Equivalent Units XXX
Cost Per Equivalent Unit:
Beginning Cost + Current Cost
Equivalent Units
Comparison of FIFO and Weighted Average
Equivalent unit calculation under FIFO consists of 3 elements representing the current periods production, whereas calculation under the weighted average method consists of only two elements
FIFO represents only cots incurred in the current period. Weighted average includes both current period plus prior period units
Operational Cost Drivers
- Volume-Based:
- Direct Labor Hours or Machine Hours
- Can Distort the amount of costs assigned to various product lines because overall overhead costs do not fluctuate with volume
- Activity Based:
- Assumes that resource-consuming activities with specific purposes cause costs
- Best way to assign indirect costs to product is based on the product’s demand for resource- consuming activities
- Attempts to improve cost allocation by emphasizing long-term product analysis
Activity- Based Costing Terminology
- Activity: any work performed inside a firm
- Resource: an elements that is used to perform ( or applied to perform an activity)
- Cost Drivers: activity bases that are closely correlated with the incurrence of manufacturing overhead costs in an activity center
- Often used as allocation bases for applying overhead costs to cost objects
- Ability to change total costs
- Include nonfinancial, statistical measurements of activities such as sales or production volume
- Resource Cost Driver: amount of resources that will be used by an activity
- Activity Cost Driver: amount of activity that a cost object will use, and it is used to assign the costs to the cost objects
- Activity Centers: operation necessary to produce a product
- Cost Pool: group of costs or specially identified cost center in which costs are grouped, assigned and collected
Characteristics of ABC
- Can be part of a job order system or process cost system
- Can be used for manufacturing or service businesses
- Takes a long-term viewpoint and treats production costs as variable
- Cost driver is often a nonfinancial variable
- May be used for internal but not for external purposes
- Also called Transaction-Based Costing when cost driver is the number of transactions involved in a particular activity
- Focuses management on the cost/benefit of activities
