1 Assumption University Graduate School of Business Guideline for Written Comprehensive Examination Professional MBA Evening Managerial Accounting (MA) Dr. Surasakdi Prugsamatz Part 1 TOPIC 1 : Classifications of Accounting: 1. Financial Accounting: to record business transactions in the books of accounts. 2. Cost Accounting: formal mechanism -costs of products or services are ascertained and controlled. 3. Management Accounting: use of accounting data collected for the purpose of policy formulation, planning, control, and decision making by the management. Cost Classification: 1. Product cost : Costs that are related to the finished products are called Product costs or unexpired costs. Characteristics of Product costs: a. It is treated as Assets. b. It is recorded as Inventory. Illustration : Merchandise Firm: Sales $75,000 Less cost of goods sold: Merchandise inventory Jan.1 $ 6,000 Add: Merchandise purchases 40,000 Total merchandise available for sale $46,000 Less: Merchandise inv. Dec.31 4,000 Cost of goods sold 42,000 Gross margin $33,000 Manufacturing Firm: Sales $75,000 Less cost of goods sold: Finished goods inventory Jan.1 $ 6,000 Add: Cost of goods manufactured 40,000 Total finished goods available for sales $46,000 Less: Finished goods inv. Dec.31 4,000 1

2 Cost of goods sold 42,000 Gross margin $33, Period costs : treated as expenses when incurred in the same period are called Period costs. Period costs are also called expired costs. Cost of goods sold, operating expenses. 3. Noninventorable unexpired costs: Costs that are treated as assets when incurred and become expenses when consumed but are not recorded as inventory are called noninventorable unexpired costs. Supplies, Prepaid rent, prepaid insurance. Characteristics: a. It is an asset. b. It is not an inventory. 4. Manufacturing costs. Manufacturing costs or production costs can be classified into: a. Raw materials: Direct materials refer to costs that can be traced or identified for one finished goods. Indirect materials: Costs that cannot be traced or difficult to trace them. b. Labor. Direct labor :costs that can be traced or identified for one finished goods. Indirect labor :costs which does not directly contribute to production. Idle time :the amount paid to workers for unproductive time. Overtime premium: amount paid in excess of normal rate. c. Factory Overhead: All manufacturing costs are classified as production costs except direct materials and direct labor. In order to control it, the management needs to set a yardstick or a benchmark for it under Traditional Costing System(TCS) which is known as standard factory overhead rate or estimated factory overhead rate, or pre-determined factory overhead rate, or a single plant-wide predetermined overhead rate. Therefore: Standard factory overhead rate is = Total estimated factory overhead costs * Selected appropriate activity base *Activity bases that are commonly used in the business consist of (Traditional system) 1. Direct labor hours worked. (DLH) 2. Direct labor costs. 2

3 3. Production volume. 4. Machine hours. 5. Prime cost and conversion costs Prime costs : They are the sum of direct materials and direct labor. Conversion costs: They are the sum of direct labor and factory overhead. Total costs = DM + DL + FOH = Prime costs + FOH = DM + Conversion costs 6. Incremental costs Incremental costs are also known as Differential costs. A differential cost is the amount by which the cost differs between two alternatives. 7. Average costs and Marginal costs Average cost per unit = Total cost of goods manufactured Number of units produced Marginal cost is the extra cost of production incurred when one more unit is produced. 8. APPRAISAL COSTS (Inspection costs ) --- Costs that are in curred to identify defective products before the products are shipped to customers. Example: Test and inspection of incoming materials Final product testing and inspection Maintenance of test equipment Supervision of testing and inspection activities 9. EXTERNAL FAILURE COSTS ---- Costs that are incurred when a product or service that is defective is delivered to a customer. Example: Warranty repairs and replacements Liability arising from legal action against a company Lost sales arising from a reputation for poor quality. 10 INTERNAL FAILURE COSTS ---- Costs that are incurred as a result of identifying defective products before they are shipped to customers. ( scrap, rejected products, reworking of defective units) Example: Re-inspection of reworked products Re-testing of reworked products Rework labor and overhead 11. PREVENTION COSTS --- Costs that are incurred to keep defects fro m occurring. Example: Systems development Quality training Quality engineering Quality circles 3

4 12. Cost Behavior Cost behavior can be classified into five common patterns namely: a. Variable costs(vc) b. Fixed cost(fc) c. Mixed cost (MC) d. Semi-fixed cost(step fixed cost) a. Variable cost (VC) Cost that changes in direct proportion to the activity but the cost per unit remains constant is called Variable cost. Characteristics: 1. Variable cost per unit (VCU)is constant. 2. Total variable cost(tvc) changes in direct proportion to the activity. b. Fixed cost Fixed costs are costs that do not change according to the level of activity but the fixed cost per unit changes inversely with the changes in volume of activity. Characteristics: 1. Total fixed cost(tfc) is constant. 2. Fixed cost per unit(f CU) changes invers ely with the changes in volume of activity. Committed fixed cos ts refer to costs that cannot be easily or quickly eliminated. Usually these costs incurred in maintaining the operating facilities and organization. Discretionary Fixed costs are costs that can be discontinued at management s discretion in a relatively short time in comparison with committed fixed costs. These costs directly reflect the top management policies and can be reduced or eliminated, if the circumstances so required. c. Mixed cost Mixed cost is the sum of total variable cost plus total fixed cost. VCU= Difference in costs Difference in activity Based on High-Low method: TFC = Total cost - Total variable cost vcu = Highest cost - Lowest cost Highest activity - Lowest activity TFC = Total costs - Total variable costs d. Semi- fixed cost 4

5 When there is an intermittent jump in the fixed cost is called semi-fixed cost. Range of activity Total fixed costs 1 unit 3,000 units $ 20,000 3,001 units - 5,000 units $25, units - 9,000 units $50,000 9,001 units - 14,000 units $120,000 RM Purchases = (LIST PRICE TRADE DISCOUNT) + freight-in PRA - PD RM used= RM BB + Net purchases RM EB RM USED = DM used+ IDM CGM = WIP INV. BEG. + DM USED + DL + FOH - WIP INV. EDING CGS = FG. Inventory beginning + CGM - FG. Inventory ending *inventory ending cost may be determined First-in, first-out (FIFO) Last-in, first-out (LIFO) Weighted average.

Costs refer to : Manufacturing costs : direct materials; direct labor; variable factory overhead; fixed factory overhead. Operating expenses: variable selling and administrative expenses; fixed selling and administrative expenses. Variable costs: DM; DL; V.FOH; V. Selling and administrative expenses. Fixed cost: F. FOH; F. selling and administrative expenses. Volume refers to: 1. Sales volume in units. 2. Total sales value. Target profit : profit earned before taxes. PBT = NI 1 - tax rate Tax rate = Tax amount PBT Break-even point: BEP is a point where there is no profit no loss. 6

7 It is considered as an indicator as it helps the management to avoid loss operation. Equation method: TOTAL REVENUE = TOTAL VARIABLE EXP. + TOTAL FIXED EXP Contribution Margin (CM) method: CM = total sales - total variable expenses. CM is the profit earned before deducting all fixed expenses. All fixed expenses are treated as period costs(expired). Fixed expenses cannot become product costs in any circumstances or conditions. Produced and sold all Produced and sold some all FC become expenses Produced and sold nothing Therefore: 1. if TCM = TFC, it is at BEP. 2. if TCM > TFC, it is a profit. 3. if TCM <TFC, it is a loss. Formula: Per unit: CMU = SP - VCU CM% = SP - VCU x 100 SP = CMU x 100 SP VC% = VCU x 100 TOTAL: SP TCM = Total Sales - Total Variable costs CM% = TS - TVC X 100 TS = TCM X 100 TS VC% = TVC X 100 TS ****CMU = Difference in net income 7

8 Equation Method: Difference in activity Total Sales - TVC - TFC = PBT Contribution Margin method X = Total fixed expenses + PBT CMU $ (Bahts) sales: X = Total fixed expenses + PBT CM% Margin of Safety (MS) MS is the excess of budgeted (or actual) sales over the break-even volume of sales. It indicates the amount by which sales can drop before losses begin to incur. The margin of safety can be expressed in amount and in percentage. M/S in amount = Total sales - Total break-even sales M/s in percentage = Total sales - Total break-even sales Total sales Operating Leverage(OL) Leverage explains how one is able to achieve a large increase in profits with only a small increase in sales and/or assets. OL refers to the ability of the firm to generate an increase in net income when sales revenue increases. It is a measure of the use of fixed costs in an organization. OL is high in companies that have a high proportion of fixed costs in relation to variable costs and the profit will be very sensitive to changes in sales. OLF = Contribution Margin Net Income Sales Mix Sales mix refers to the relative proporti on in which a company s products are sold. OVERALL VC% = OVERALL VARIABLE 8

9 OVERALL SALES OVERALL CM% = OVERALL CM OVERALL SALES Units sold: Weighted average CMU = (cmu of A x SMR of A) + (cmu of B x SMR of B) + BEP = Fixed expenses Weighted average CMU Therefore: Units sold of product A at BEP = SMR of A x BEP units Units sold of product B at BEP = SMR of B x BEP units Dollars( bahts) sales: Overall CM% = Total overall CM Total overall sales BEP in amount = Fixed expenses Overall CM ratio CVP Analysis ( under ABSORPTION COSTING) BEP = TFC + Profit + (Qs- Qp) x fixed OH rate CMU.. 9

10 Activity-based-costing System. (ABC) ABC is a cost planning system. It identifies the activities and the cost of the resources needed to perform. It then assigns the cost of the activities to product or service that uses them. It has been designed to show the relationship between the company's activities and the resources needed to carry them out. It concentrates on the activities rather than the costs. It focuses on indirect costs especially factory overhead costs. As a result, managers can identify the greatest value added activities for efficient productions and eliminate the non-value added activities. Comparison of Conventional and Activity- Based Costing System Conventional Costing System 1. Single unit based cost driver Activity Based Costing System 1. Multiple unit and Non unit based driver 2.

16 To select and examine those key activity work processes critical to the success of the organization. Activities are defined, analyzed, and cost to determine the situation. To monitor the result of improvement initiatives. To provide the feedback necessary sustains improvement initiatives. To evaluate outsourcing of activities To effect strategy deployment. To determine value-added and non-value-added activity cost. To cut cost / downsize or restructures operations. To budget and support the expected sales volume or other requirements of the business. To determine and optimize activity capacity of each key and significant activity performed. To isolate / eliminate cost driver To estimate / bid on customer work to meet the customer s requirement would be identified first. Benefit of Activity-Based Management Enhance efficiency. I ncrease the efficiency of your o rganization s resources by using operational ABM. Lower costs. One way to lower costs is to consolidate purchasing. Enhance asset usage. Leverage your equipment and people to get better usage of their talents. Improve or eliminate faulty activiti es or processes. Look at the speed at which a purchased product can get to your members. Eliminate unprofitable products / services. Expand demand of profitable products and services. Choose suppliers that are low-cost, not just low-price. Activity-Based Management is co mmon sense, systematic method of planning controlling and improving labor and overheard cost. ABM s purpose is to control co sts and profits for a project a nd activity Weaknesses of Activity-based Management Time consuming. To implement an ABM system will be wasted if no one uses or takes action on the information provided The value and benefit of ABM can be difficult to quantify. 16

17 SPECIAL DECISION: 2 alternatives non-recurring (less frequent occurance) short term decision: Management needs INFORMATION: QUANTITATIVE (OBJECTIVE)******* QUALATATIVE (SUBJECTIVE)***GIVEN*** There TWO types of information namely: RELEVANT COSTS INFORMATION (RC) IRRELEVANT COSTS INFORMATION (IRC) RELEVANT COST (RC): Characteristics: 1. It must be related to the future events. 2. It should differ among alternatives. Example: AVOIDABLE COST OPPORTUNITY COST IRRELEVANT COST(IRC): Characteristics: 1. It is related to the past or the present events. 2. It is the same among alternatives. Example: Sunk cost, unavoidable cost, capacity cost, allocated cost (joint costs), committed costs. COSTS: VC (VCU is constant) AND FC (TFC is constant) UNDER NORMAL CONDITIONS: 17

18 TVC are classified as RC. TFC are classified as IRC. Exception: TVC will become IRC when TVC remain constant. TFC will become RC when TFC change. TYPES OF DECISION MAKING: 1. MAKE OR BUY DECISION. 2. SPECIAL ORDER DECISION. 3. JOINT PRODUCTS DECISION. 4. ADD OR DROP DECISION. 5. Profit maximization through capacity utilization 1. MAKE OR BUY DECISION: Make or b uy decision refers to the parts or components of a finished product. The final decision depends upon the COST SAVING. The alternative that yield the highest cost saving will be selected. COST OF INDIFFERENT POINT: COST OF MAKE = COST OF BUY 2. SPECIAL ORDER DECISION: Management will decide whether to accept or to reject the special order or not, depends upon : Profit earned from the special order. Adequate of idle capacity. Characteristics: 1. One time potential buyer in large quantity. 2. Will not affect the regular market. 3. It s not for reselling. It is meant for personal use. 4. Price requested by potential buyer w ill be much low er than the curren t normal selling price.(price OFFERED) STEP 1: Relevant VC CMU = Price offered - (DM +DL + V.FOH + V. Operating) = $ = $ STEP 2: TCM = CMU x Special order quantity = $ x units = $ STEP 3 PROFIT = TCM - Relevant TFC = $ - $ = $ 18

19 3. JOINT PRODUCTS DECISION: When 2 or more prod ucts are produced simultaneously in a single process, we called it as JOINT PRODUCTS. SPLIT OFF POINT is a point where the individual product can be identified. JOINT COSTS (common costs or combine d costs) ---refer to co sts that are incurred for 2 or more products that produced simultaneously in a single process. SEPARABLE COSTS refer to additional costs incurred for processing the individual product further. Product Sell at SOP Sell after SOP Profit= Sales - SC Profit = Sales SC C (at sop) Profit after joint cost = gross profit Separable cost = variable CGS Joint costs = fixed CGS = IRC JOINT COSTS ALLOCATION: (based on production volume) 1. PHYSICAL (production) UNITS METHOD: A : B : C 7000 UNITS : 5000 UNTIS : 8000 UNITS(production) 7 : 5 : 8 A s JC = 7/20 x $220,000 = $77,000 B s JC = 5/20 x $220,000 = $55,000 C s JC = 8/20 x $220,000 = $88, Relative sales value (of production vol ume) at split off point: (production volume x sp) A : B : C 7000 UNITS x $20 : 5000 UNTIS x $12 : 8000 UNITS x $16 =$ 140,000 =$60,000 = $128, : 60 : 128 A s JC = 140/328 x $220,000 = $ 93,902.4 B s JC = 60/ 328 x $220,000 = $40,243.9 C s JC = 128/ 328 x $220,000 = $85,

20 4. ADD OR DROP DECISION: As consumers change their preferences, the business firms have to decide whether to add or to drop a product or product line. The management s decisio n depend upon the profit of the company w hich can be det ermined by determine an income statement contribution margin approach. Note: 1. If TCM is positive Don t drop or Add 2. If TCM is negative -----Drop or Don t Add 3. If I/S is profit Add or Don t drop 4. If I/S is loss and if TCM > Relevant TFC Don t drop 5. If I/S is loss and if TCM < Relevant TFC-----Drop 5. Profit maximization through utilization of capacity decision Normally the capacity of any organization is limited. Therefore management needs to determine alternatives that can yield the maximum profit with limited capacity. Ex 1: Total capacity available = 10,000 mh. Company can utilized the capacity to produce either Product A, B, or C. Product A Product B Product C Selling price $15 $23 $30 DM $4 $5 $6 DL V.FOH Total VCU $9 $18 $21 DMH per unit 1 hour 2 hours 3 hours Product A Product B Product C CMU 15-9= $6 $23 18= $5 $30-21= $9 CM/hr. $6/1hr= $6 $5/ 2hrs. = $2.50 $9/ 3hrs.= $3 FEXIBLE BUDGET AND VARIANCE ANALYSIS Characteristic of Performance report: a. Report must be prepared according to the assigned responsibilities and authority. b. Clearly differentiated between controllable and noncontrollable items for fair measurement. c. Timely report. d. Comparison of actual results and planned results. Current period Year-to-date Costs Actual Budget Variance Actual Budget Variance 20

21 DM DL V.FOH F. FOH Total Standard Cost Standard costing is a technique of cost accounting which compares the standard cost of each product or service with actual cost in order to determine the efficiency of the operation and any remedial action may be taken immediately. The purpose of setting Standard costs is for controlling costs, pricing decision, performance appraisal, cost awareness, and management by objective. So the current attainable standard can be determined by using previous period actual result + adjustments required and can be subdivided into standard quantity and standard price. Flexible Budget Performance Report Actual Flexible Budget Variance Production 1,200 units 1,200 units ---- Direct Materials Direct labor FOH Analysis of Budget Variances APV x actual DM used/unit x actual DM price/lb 1,200 units x 4.2 lbs x $4.90/lb =$24,696 FBPV x Std DM used/unit x std DM price/lb 1,200 units x 4lb x $5/lb = $24,000 =$696 U Advantages of Variance Analysis: 1. Aid in inventory costing. 2. Assist in decision making. 3. Selling price formulation based on what costs should be. 4. Aid in coordinating by having all departments focus on common goals. 5. Set and evaluate enterprise objectives. 6. Cost control and performance evaluation by comparing actual to budgeted figures. 21

22 7. Highlight problem areas through the management by exception principle. 8. Pinpoint responsibility for undesirable performance so that corrective action may be taken. 9. Act in motivating employees to accomplish predetermined goals. 10. Facilitate communication within the organization such as between top management and supervisors. 11. Assist in planning by forecasting needs such as cash requirements. 12. Establish bid prices on contracts. 13. Simplify bookkeeping procedures by keeping the records at standard costs. Direct material Variance (DMV) 1. Direct material price variance (DMPV) DMPV = (Actual price x Actual DM qty purchased) - ( Standard Price x Actual DM qty purchased) 2. Direct material quantity (efficiency) variance(dmqv) Actual DM qty used = Actual level of activity x Actual DM qty used per unit Standard DM qty used = Flexible budget level of activity x Standard DM qty used per unit DMQV=(Actual qty used x Standard price) - (Standard qty used x Standard price) Therefore : DMV = DMPV + DMQV Reasons for material price and quantity variances: 1. Overstated price paid. 2. Failure to take discounts. 3. Improper specifications. 4. Use of a lower grade material purchased to economize on price. 5. Uneconomical size of purchase orders. 6. Failure to obtain an adequate supply of a needed variety. 22

23 7. Purchase at an irregular time or sudden and unexpected purchase required. 8. Poor mix of materials, poorly trained workers, improper adjusted machines. 9. Substitute of nonstandard materials, poor product design or production technique. 10. Lack of proper tools or machines, carelessness in not returning excess materials to storeroom, unexpected changes in volume. 11. Failure to detect defective goods. 12. Inefficient labor, poor supervision, or waste on the production line. 13. Inaccurate standard price. 14. Excessive transportation charges or too small a quantity purchased. 15. Insufficient quantity bought because of a lack of funds. Direct Labor Variance (DLV) 1. Direct Labor Rate Variance (DLRV) AH = Actual level of activity x Actual direct labor hour per unit SH = F.B. level of activity x Standard direct labor hour per unit BH = M.B. level of activity x Standard direct labor hour per unit DLRV =(Actual DL rate/ hour x AH) - (Std DL rate/ hour x AH) 2. Direct Labor Usage(Efficiency) Variance (DLUV) DLUV = (AH x Std DL rate/ hr) - ( SH x Std DL rate/ hr) Therefore: Total DLV = DLRV + DLUV Reasons for Direct labor rate and usage variances: 1. Increase in wages. 2. Poor scheduling of production resulting in overtime work. 3. Use of workers commanding higher hourly rates than expected. 4. Poor supervision. 5. Use of unskilled workers paid lower rates or the wrong mixture of labor for a given job. 6. Use of poor quality machinery. 7. Improperly trained workers. 8. Poor quality of materials requiring more labor time in processing. 9. Machine breakdowns. 10. Employee unrest. 11. Production delays due to power failure. 12. Use of overpaid or excess number of workers. 13. Overtime and poor scheduling of production. Variable Factory Overhead Variance (VFOH. V) 23

24 1. Variable factory overhead spending variance (VFOH. SV.) VFOH. SV. = Total actual VFOH paid - ( AH x Std VFOH rate/ hr) 2. Variable factory overhead efficiency variance (VFOH. EV.) VFOH. EV. = (AH x Std VFOH rate/hr) - (SH x Std VFOH rate/hr) *Std VFOH rate/hr applied = Total VFOH cost budget MBPV x Std dl hr/unit Controllable (Budget) Variance Total Budget variance = VFOH. SV. + VFOH. EV. 3. V. factory overhead volume (denominator) variance (VFOH. VV.) VFOH. VV. = (Std VFOH rate/hr based on FB.) - (Std VFOH rate/hr applied MB. ) x SH =(Std VFOH rate/hr x SH) - (Std VFOH rate/hr x SH) Total VFOH variance = VFOH. SV. + VFOH.EV. + VFOH.VV. Fixed Factory Overhead Variance (FFOH.V) 1. Fixed factory overhead spending variance (FFOH.SV.) total actual direct labor hour. FFOH.SV.= Total actual FFOH costs - Total FB.FFOH costs based on AH 2. Fixed factory overhead efficiency variance (FFOH. EV) FFOH. EV. = FB.FFOH. based on AH - FB.FFOH. based on SH = Zero 3. Fixed factory overhead volume(denominator) variance (FFOH.VV) *Std FFOH rate/hr applied = Total FFOH cost budget MBPV td DLH/ x S unit F.FOH VV. = F.FOH BUDGET ( SH x Std F.FOH rate per hour) 24

25 Reasons for factory overhead spending, efficiency and volume variances: 1. Buying the wrong size plant. 2. Improper scheduling. 3. Insufficient orders. 4. Shortages in material. 5. Machinery failure. 6. Long operating time. 7. Inadequately trained workers. $%$%$%$%$%$%$%$ 25
