Please summarize the basic points of financial accounting: Users/ Time focus/ Emphasis/ Importance/ Subject focus/ Requirements. (1) Is the information provided by financial accounting enough for an enterprise to conduct its operation and management? (2) If not, how to satisfy this demand for the internal used information? (3) Have you ever heard “managerial accounting”? What is Managerial Accounting? Managerial accounting is an activity that provides financial and nonfinancial information to managers and other internal decision makers. It is quite important to planning, control, and decision making activities. Comparison between Managerial Accounting and Financial Accounting Managerial accounting and financial accounting can be compared as the following table: Financial Accounting Managerial Accounting 1. Users Investors, creditors, and other external users Managers, employees, and other internal users 2. Time focus Historical perspective Future emphasis 3. Emphasis Objectivity and Verifiability Relevance for planning and control 4. Importance Precision of information Timeliness of information 5. Subject focus Summarized data for the whole organization Detailed segment reports of an organization 6. Requirements Structured and often controlled by GAAP Relatively flexible (no GAAP)

Task Team of FUNDAMENTAL ACCOUNTING School of Business Sun Yat-sen University Cost classifications Costs can be classified by relevance, behaviour, controllability, traceability, and function Costs Classification by Relevance If costs influence a decision, we call them relevant costs such as costs that are applicable to a particular decision, costs that should have a bearing on which alternative a manager selects, costs that are avoidable future costs that differ between alternatives If costs do not influence a decision we call them irrelevant costs Sunk costs means that all costs incurred in the past that cannot be changed by any decision made now or in the future. They are irrelevant, and should not be considered in decisions. For example: You bought an automobile that cost $30,000 two years ago. The $30,000 cost is sunk ecause whether you drive it, park it, trade it, or sell it, you cannot change the $30,000 cost Out-of-pocket costs require future outlays of cash, they are associated with a particular decision, and are relevant for future decisions. For example: Considering the decision to take a vacation or stay at home, if you choose a vacation, you will only have travel costs(out-of-pocket costs Opportunity costs means the potential benefit that is given up when one alternative is selected over another. For example: If you were not attending college or university, you could be earning $25,000 per year. Your opportunity cost of attending college or university for one year is $25,000 Costs Classification by Behaviour Cost behavior refers to how a cost will react to changes in the level of business activity. Fixed costs do not change when activity changes; variable costs change in proportion to changes in the volume of activity. Total fixed costs remains unchanged when activity changes within a relevant range. Fixed costs per unit decline as activity increases Total variable costs change when activity changes. Variable costs per unit do not change as actIv Ity Mixed costs contain a combination of fixed and variable costs Step-wise costs remain fixed over limited ranges of volumes but increase by a lump sum when volume increases beyond maximum amounts. For example: additional production supervisors must be added when another shift is added Costs Classification by Controllability Controllable costs vs not controllable costs depend upon the employee's responsibilities. For example: A lower level manager may have control over overtime costs but not over the purchase of high-cost machinery Costs Classification by Traceability Traceable costs are classified as(1)direct costs can be conveniently traced to a unit of product or other cost objective, for examples: salaries of production workers, salary of maintenance department employees;(2)indirect costs must be allocated to a unit of product or other cost objective, for examples: factory rent, factory light and Costs Classification by Function Manufacturing costs are necessary and integral to the production of finished goods, for examples: direct labour, direct materials, and manufacturing Non-manufacturing costs are not integral to the manufacture of finished goods. For examples selling and administrative expenses Manufacturing costs can be further classified as(1)direct materials, materials that are clearly

Costs Classification by Traceability Traceable costs are classified as (1) direct costs can be conveniently traced to a unit of product or other cost objective, for examples: salaries of production workers, salary of maintenance department employees; (2) indirect costs must be allocated to a unit of product or other cost objective, for examples: factory rent, factory light and heat, factory accounting costs. Costs Classification by Function Manufacturing costs are necessary and integral to the production of finished goods, for examples: direct labour, direct materials, and manufacturing overhead. Non-manufacturing costs are not integral to the manufacture of finished goods. For examples: selling and administrative expenses. Manufacturing costs can be further classified as (1) direct materials, materials that are clearly

It is quite flexible in the number of products they can produce, where jobs involving the production of more than one unit of product are called job lots. Please refer to ppt page 27 and Process Cost Accounting Systems Process cost accounting sy stems are used for production of small, identical, low-cost items, for example, mass produced in automated continuous production process. Here costs cannot be directly traced to each unit of product. Please refer to ppt page 30 To determine the cost of goods transferred from department to department and to finished goods, we need to calculate unit cost. Unit cost is computed by dividing the accumulated costs by the number of equivalent units produced in the period. Costs are accumulated for a period of time by process or department Equivalent units is a concept expressing a number of partially completed units as a smaller number of fully completed units. For example: Three one-third full pitchers are equivalent to one all pitcher. Equivalent units may be different for material and labour and overhead at different Comparing Job Order and Process Production We can compare job order and process cost accounting systems as follows Similarities: (1)Same objective, to determine the cost of products;(2) Same inventory accounts, raw materials, goods in process, and finished goods; (3) Same overhead assig Differences Job order systems vs process sy stems:(1)Custom orders vs Repetitive production;(2) Heterogeneous products vs Homogeneous offering; (3)Low output volume vs standardization vs High standardization Cost allocation Based on the complexity from low to high, the methods of cost allocation can be classified

Cost Allocation Based on the complexity from low to high, the methods of cost allocation can be classified as plant-wide overhead rate, two-stage cost allocation, and activity-based costing

Task Team of FUNDAMENTAL ACCOUNTING School of Business Sun Yat-sen University Plant-wide Overhead Rate A single plant-wide overhead rate is relatively easy to use, but ay result in inaccurate product costs Two-stage Cost Allocation Two-stage cost allocation is more accurate method than Stage 1: Allocate service department costs to production departments. Service department costs are assigned to operating(or production) departments Stage 2: Allocate production department costs to cost objects. Costs accumulated within operating(or production)departments are assigned to cost object Activity-based Costing Activity-based costing attempts to better allocate costs to the desired cost objects by focusing on activities consumed by the cost objects. Many activities within a department drive overhead costs. Products require activities. Activities consume resources Activity-based Costing: Procedures The procedures include: (1)Identify activities that consume resources;(2)Assign costs to a cost pool for each activity; (3)Identify cost drivers associated with each activity;(4) Compute overhead rate for each cost pool, rate equals to estimated overhead costs in activity cost pool over to estimated number of activity units; (5) Allocate overhead cost, overhead rate times actual activity Activity-based Costing: Identifying Cost Drivers Most cost drivers are related to eit volume or complexity of production For example: purchasing, invoicing, quality inspection, product design Three factors must be considered in choosing a cost driver: (1) Causal relationship; (2) Benefits received; (3)Reasonableness The typical costs and cost drivers are listed as follows Cost driver Materials purchasing umber of purchase orders Materials handlin lumber of materials requisitions umber of employees uipment amortization Number of products produced or hours of use Quality inspection umber of units inspecte Indirect labour in setting unNumber of setups required Activity-based Costing: Benefits The benefits of activity-based costing include:(1) More detailed measures of costs; (2)Better understanding of activities; (3) More accurate product costs for pricing decisions, product elimination decisions, and managing activities that cause costs Certainly, benefits should al ways be compared with costs of implementation ABC Company acquired its factory building about 25 years ago. For a number of years, the company has rented out a small, unused part of the building The renter's lease will expire soon

Activity-based Costing: Identifying Cost Drivers Most cost drivers are related to either volume or complexity of production. For example: purchasing, invoicing, quality inspection, product design. Three factors must be considered in choosing a cost driver: (1) Causal relationship; (2) Benefits received; (3) Reasonableness. The typical costs and cost drivers are listed as follows: Cost Cost Driver Materials purchasing Number of purchase orders Materials handling Number of materials requisitions Personnel Number of employees Equipment amortization Number of products produced or hours of use Quality inspection Number of units inspected Indirect labour in setting up equipment Number of setups required Activity-based Costing: Benefits The benefits of activity-based costing include: (1) More detailed measures of costs; (2) Better understanding of activities; (3) More accurate product costs for pricing decisions, product elimination decisions, and managing activities that cause costs. Certainly, benefits should always be compared with costs of implementation Case Study ABC Company acquired its factory building about 25 years ago.
