4. The meaning of costs
LO1
A cost is the sacrifice made to achieve a particular purpose.
There are different costs for different purposes.
 An expense is the cost incurred when an asset is used up or sold to generate revenue.
"product cost" and "period cost " describe timing with which expenses are recognized.

5. LO2
The meaning of costs
Product costs are the costs of goods manufactured or the cost of goods purchased for resale. These costs are inventoried until the goods are sold.
Period costs are all other non-product costs in an organization (e.g., selling and administrative). Such costs are not inventoried but are expensed as time passes.

6. COSTS ON FINANCIAL STATEMENTS
LO3
COSTS ON FINANCIAL STATEMENTS
Product costs, kept on the balance sheet until sale, are found in three inventory accounts:
Raw materials—materials that await production
Work in process—partially completed production 
Finished goods—completed production that awaits sale
Product costs are shown as cost of goods sold on the income statement when goods are sold.

7. MANUFACTURING OPERATIONS AND COSTS
LO4
MANUFACTURING OPERATIONS AND COSTS
There are various types of production processes example:
Job shop—low production volume, little standardization; one-of-a-kind products (movies, service, custom-made home)
Batch—multiple products; low volume (bakery, airplanes)
Assembly line—a few major products; higher volume (automobiles, TV) 
Mass customization—high production volume; standardized components; customized combinations of components (Dell computers)
Continuous flow—high volume; highly standardized commodity products (Oil & Gas)

8. MANUFACTURING OPERATIONS AND COSTS
LO4
MANUFACTURING OPERATIONS AND COSTS
In mass customization, many standardized components are combined to produce custom-made goods to customer order.
Production is triggered by the placement of a customer order, which often takes place via the Internet.
Inventories of finished goods and raw materials are relatively low, because raw materials are ordered only when needed in manufacturing and product is shipped as soon as it is completed.

9. MANUFACTURING OPERATIONS AND COSTS
LO5
MANUFACTURING OPERATIONS AND COSTS
There are 3 types of manufacturing costs:
Direct materials—materials easily traced to a finished product (e.g., the seat on a bicycle)
Direct labour—the wages of anyone who works directly on the product
Manufacturing overhead—all other manufacturing costs such as: Indirect materials, indirect labour, and other manufacturing costs not easily traceable to a finished good (e.g., insurance, property taxes, depreciation, utilities).

10. MANUFACTURING OPERATIONS AND COSTS
LO5
MANUFACTURING OPERATIONS AND COSTS
Overtime premiums and the cost of idle time are also accounted for as overhead.
Conversion cost (the cost to convert direct materials into finished product): direct labour + manufacturing overhead
Prime cost: direct material + direct labour

11. MANUFACTURING COST FLOWS
Manufacturing costs (DM, DL, and MOH) "put in process" and attached to work-in-process (WIP) inventory.
Cost of goods manufactured: DM used + DL + MOH + beg WIP – end WIP . This amount is transferred from WIP inventory to F/G inventory when goods are completed.
The costs are then transferred from F/G inventory to CGS upon sale of the goods.

12. MANUFACTURING COST FLOWS
Product costs and cost of goods sold for a manufacturer:

13. MANUFACTURING COST FLOWS
Manufacturers generally prepare a schedule of CGM and a schedule of CGS
Production-cost concepts are applicable to service businesses and nonprofit organizations. For example, the DM concept can be applied to the food consumed in a restaurant or the jet fuel used by an airline. Similarly, DL would be equivalent to the cooks in a restaurant and the flight crews of an airline.

14. DIFFERENT COSTS FOR DIFFERENT PURPOSES
LO7
DIFFERENT COSTS FOR DIFFERENT PURPOSES
The most important classification involves how costs change in relation to changes in the activity of the organization (a measure of the output of products and services).
The activities that cause costs to be incurred are called cost drivers. Examples include labour hours in manual assembly work and machine hours in automated production settings.
The higher the degree of correlation between a cost increase and the increase in its cost driver, the better the cost management information.

15. Variable and fixed costs
LO8
Variable and fixed costs
Total Variable Costs move in direct proportion to a change in activity. For example, the total cost of bicycle seats goes up in proportion to the number of bicycles produced.
Total Fixed Costs remain constant in total as the level of activity changes. For instance, property taxes for the manufacturing facilities remains the same whether 100 bicycles or 1,000 bicycles are produced.

16. Total Variable Cost Example
The bicycle seat bill is based on how many bicycles are made.
Total Bicycle Seat Bill
Bicycles Made

17. Variable Cost Per Unit Example
The cost per bicycle seat is constant.
Per Seat Charge
Bicycles made

18. Total Fixed Cost Example
Your monthly property tax bill does not change when you make more bicycles.
Number of Bicycles Made
Monthly Charge for Property Taxes

19. Fixed Cost Per Unit Example
The average cost per bicycle for property taxes decreases as more bicycles are made.
Monthly Property Tax per Bicycle Made
Number of Bicycles made

20. Direct and indirect costs
LO9
Direct and indirect costs
An entity (e.g., a specific product, service, or department) to which a cost is assigned is commonly known as a cost object.
A direct cost is one that can be easily traced to a cost object (faculty’s salaries).
An indirect cost is a cost that cannot be easily traced to a cost object (president’s salary).
A cost management system traces costs to objects that caused them so that managers can isolate responsibility for spending and objectively evaluate operations.

21. Controllable and uncontrollable costs
LO9
Controllable and uncontrollable costs
Controllable costs—costs over which a manager has influence (e.g., direct materials)
Uncontrollable costs—costs over which a manager has no influence (e.g., property taxes)

22. DIFFERENT COSTS FOR DIFFERENT PURPOSES
LO10
DIFFERENT COSTS FOR DIFFERENT PURPOSES
Opportunity cost—the benefit forgone by choosing an alternative course of action (e.g., wages forgone when attending university rather than working)
Out-of-pocket cost—a cost that requires a cash outlay
Sunk cost—a cost incurred in the past that cannot be changed by future action (e.g., tuition)
Differential cost—the net difference in cost between two alternative courses of action
Incremental cost—the increase in cost from one alternative to another

23. COSTS IN THE SERVICE INDUSTRY
LO10
COSTS IN THE SERVICE INDUSTRY
The preceding costs discussed in a manufacturing context are just as relevant for service providers.
Although manufacturers and service firms are in very different businesses, they all must understand their costs in order to be successful in a competitive environment.

24. Costs and Benefits of Information
More information does not mean more benefits if information overload results.

Add: Units started during the month
2,400
Less: Units partially completed at end of month
(ending WIP inventory)
