Exhaustive Guide to Cost and Management Accounting Systems

Introduction to Cost Accounting Concepts and Definitions

• Definition of Cost Accounting: Cost accounting is a tool of management that provides detailed records of costs relating to products, operations, or functions. It refers to the process of determining and accumulating the cost of a particular product or activity. It encompasses the classification, analysis, and interpretation of costs.

• Types of Costs Determined:     * Estimated Future Costs: Used specifically for planning purposes.     * Actual (Historical) Costs: Used for evaluating past performance.

• ICMA (London) Definition: Cost accounting is defined as "the process of accounting for cost from the point at which expenditure is incurred or committed to the establishment of its ultimate relationship with cost centres and cost units. In its widest usage it embraces the preparation of statistical data, the application of cost control methods and the ascertainment of the profitability of activities carried out or planned."

• Costing as a Technique: Costing is described as a technique by which the price of a product can be determined. It involves proper control over the three core elements of cost:     1. Material     2. Labour     3. Overheads

• The Scope of Cost Accounting: It is an art of determining cost and generally includes:     * Cost control and cost consciousness.     * Determination of product unit cost.     * Profit and loss for various products.     * Inventory valuation.

Cost Accounting in India: Legislative and Historical Context

• Establishment of Body: The Institute of Cost and Works Accountants was established in 1944. It was registered as a limited company with the primary object of training in cost accounts through examinations.

• Industrial Policy Influence: Post-independence, new industrial policies framed in India led to faster industrial growth and increased the need for systematic cost records.

• Legislative Mandate: In 1965, the Government of India amended the Companies Act to authorize the issuance of notifications requiring mandatory maintenance of cost accounts for specific manufacturing industries. The Government can also order audits of these cost accounts.

• Reasons for Late Development in India:     1. Simplicity of Early Business: Until the late 19th/early 20th century, manufacturing processes were simple with limited variety.     2. Low Indirect Costs: Overhead components were historically small as costly machinery was uncommon.     3. Secrecy: A tendency among cost accountants to keep methods strictly secret.

Definitions of Key Terms: Cost, Costing, and Cost Accountancy

• Definition of "Cost":     * Oxford Dictionary: "The price paid for something."     * C.I.M.A. England: "The amount of expenditure (actual or notional) incurred on or attributable to a given thing."     * W.M. Harper: "A cost is the value of economic resources used as a result of producing or doing the thing costed."     * CAS 1 (Exposure Draft): "Cost is a measurement in monetary terms of the amount of resources used for the purpose."

• Distinction Between Cost, Expenses, and Losses:     * Expense: Expired costs deductible from revenue (e.g., depreciation, rent, interest). These involve consumed service potential of an asset.     * Deferred Costs (Assets): Unexpired costs for which economic benefit is yet to be received (e.g., prepaid insurance, preliminary expenses).     * Losses: Expired costs resulting from a decline in service potential that generated zero benefit (e.g., theft, fire).

• Definition of "Costing":     * Harold J. Wheldon: Classifying, recording, and allocating expenditure to determine costs of products/services and presenting data for control/guidance. It includes the ascertainment of cost for every order, job, contract, process, or unit.     * C.I.M.A. England: "The technique and process of ascertaining cost."     * W.W. Bigg: Classifying, recording, and allocating expenditure to determine costs, their relation to sales value, and profitability.

• Definition of "Cost Accounting":     * Carter: A system of recording accounts of material used and labour employed in manufacture of a commodity or job.     * C.I.M.A. England: The application of accounting and costing principles, methods, and techniques to ascertain costs and analyze savings/excesses against experience or standards.

• Definition of "Cost Accountancy":     * C.I.M.A. England: "The application of costing and cost accounting principles, methods and techniques to the science, art and practice of cost control. It includes the presentation of information derived there from for the purpose of managerial decision-making."     * Nature: It is a 'Science' (systematic knowledge) and an 'Art' (involves techniques like marginal costing).

Objectives and Scope of Cost Accounting

• Primary Objectives:     1. Determine Product Costs: Total cost and unit cost for inventory valuation and pricing.     2. Planning and Control: Providing data to evaluate alternative plans and establish budgeted vs. actual balance.     3. Information for Decisions: Supplying data for non-recurring decisions like "Make or Buy."

• Maintenance of Control Process:     1. Comparing actual performance with budgets/standards.     2. Analyzing variance (differences) by cause and responsibility.     3. Providing managers with performance reports.

• Detailed Scope:     * Cost Ascertainment: Total/per unit cost for factory items or specific jobs.     * Cost Control: Setting standard/budgeted costs before production to ensure actuals do not exceed them.     * Cost Reduction: Continuously striving to reduce costs while maintaining quality.     * Decision Making: Estimating profitability, determining selling prices, calculating tender quotes, and identifying non-profitable departments.     * Statutory Compliance: Meeting legal requirements under the Companies Act in India.

Organizational Scope: Cost Centres and Cost Units

• Cost Centre: An organizational segment or area for which it is desirable to accumulate costs but which does not generate revenue. C.I.M.A. defines it as "a location, persons, or item of equipment (or group of these) for which costs may be ascertained and used for the purpose of control."

• Types of Cost Centres:     1. Personal: Consists of a person or group (e.g., a foreman).     2. Impersonal: Consists of a location or equipment (e.g., a store or a machine).     3. Process: Consists of a specific process or sequence of operations.     4. Production: Where actual manufacturing occurs.     5. Service: Ancillary units rendering service to production centres.     6. Operation: Consists of machines/persons performing similar operations.

• Cost Unit: A unit of quantity of product, service, or time (e.g., per tonne, per bag, per passenger kilometre).

• Examples of Cost Units by Industry:     * Cement: Per tonne or per bag.     * Sugar: Per quintal.     * Textile: Per metre.     * Bicycle: Number.     * Transport: Per tonne km or per passenger km.     * Hotel: Per room day.     * Electricity: KWH ($\text{kilowatt-hour}$).

Procedure for Installing a Costing System

1. Study of Technical Features: Analyze materials, market, labour nature, plant capacity, and demand.

2. Selection of Method: Choose the most suitable method based on organizational needs.

3. Identifying Cost Centres: Define locations, equipment, or personnel for cost accumulation.

4. Determination of Cost Units: Establish the quantity basis (simple or composite).

5. Deciding Procedure: Tailor the extensive/simple procedure to business size.

6. Proformas: Prepare standard samples (often in different colours for identification).

7. Controls: Establish efficient systems for material purchase/storage, labour efficiency, and expense monitoring.

8. Reporting: Fix proformas for weekly/monthly reports on wastage, idle time, and utilization.

9. Status of Cost Accountant: Define hierarchy; ideally responsible directly to the Managing Director to avoid lower-level pressure.

Cost Accounting vs. Financial Accounting

Deficiencies of Financial Accounting

• Lack of Classification: No separate figures for departments or processes.

• Material Control: Weak control leads to wastage and misappropriation.

• Labour Motivation: Lack of classification prevents effective incentive schemes.

• Direct vs. Indirect: Fails to distinguish controllable and non-controllable expenses.

• Fixed Prices: Does not provide accurate cost figures for scientific price fixing.

• Idle Plant: Cannot assess the loss resulting from a plant operating below capacity.

• Outside Agencies: Providing inadequate cost data to banks or government.

Principles of Overhead (Indirect Costs)

• Definition: Overhead costs are operating costs that cannot be traced directly to a particular unit of output. It is the aggregate of indirect materials, indirect wages, and indirect expenses. Synonymously used with "burden" or "supplementary costs."

• Growth of Overheads: Modernization has decreased direct labour costs and increased overheads. A survey by Henry Schwarzbach shows overheads range from $2\%$ to $67\%$, with an average of $29\%$.

• Classification of Overheads:     1. Elements: Indirect Material, Indirect Labour, Indirect Expenses.     2. Functional: Factory, Administrative, Selling, and Distribution.     3. Controllability: Controllable vs. Uncontrollable.     4. Normality: Normal vs. Abnormal.     5. Variability: Fixed, Variable, and Semi-variable.

• Fixed vs. Variable Overheads:     * Variable: Varies in total in direct proportion to volume of activity; constant per unit.     * Fixed: Constant in total over a range of activity; decreases per unit as output increases.

Procedures for Distributing Overheads

1. Codification: Assigning 'Standing Order Numbers' to each overhead item and code numbers to departments.

2. Collection: Gathering data from Store Requisition Slips, Job Cards, Vouchers, and Cash Books.

3. Allocation: Charging overhead items directly to a cost centre when they relate solely to it.

4. Apportionment: Distributing common overheads across multiple departments using an appropriate basis:     * Property Value: For fire insurance premiums.     * Area Covered: For rent, electricity (if no meter), and cleaning.     * Number of Employees: For canteen, hospital, and welfare costs.     * Machine Hours: For depreciation and repairs of machines.     * Direct Labour Hours: For supervision costs.

5. Absorption: Charging overheads to individual jobs using a predetermined rate (e.g., per machine hour or direct labour hour).

Management Accounting: Origin and Definition

• Origin: Formally described in 1950 by the Anglo-American Council of Productivity. It is considered "the language of business."

• NAA (USA) Definition: "The process of identification, measurement, accumulation, analysis, preparation and communication of financial information used by management to plan, evaluate, and control within the organization and to assure appropriate use and accountability for its resources."

• Salient Features:     * Integrated system using financial/cost accounting, stats, and economics.     * Service function providing both financial and non-financial information.     * Heavily focuses on the future and cause-and-effect relationships.

• Core Management Process:     * Planning: Formulating activity to achieve goals.     * Controlling: Monitoring implementation and taking corrective action using feedback.     * Decision-making: Choosing best solutions among alternatives.     * Worker Enablement: Giving authority to operational staff to move toward continuous improvement (High Involvement Organization - HIO).

Decision-Making Scenarios in Management Accounting

• Operating Decisions (Short-term):     1. Price Determination: Setting the Minimum Price ($\text{Variable Cost} + \text{Fixed Cost}$) during competition.     2. Special Orders: Accepting or rejecting orders below total cost. Rule: Accept if \text{Price} > \text{Variable Cost}, provided idle capacity exists.     3. Shut Down Point: $\text{Shut Down Point} = \frac{\text{Net Escapable Fixed Cost}}{\text{Contribution per unit}}$.

• Organisational Decisions (Long-term):     1. Make or Buy: Comparing internal production cost vs. market purchase price.     2. Buy or Hire: Evaluating profitability of purchasing a machine vs. leasing it.     3. Product Replacement: Replacing an existing product with a more profitable one based on marginal contribution.     4. Further Processing: Processing semi-finished goods only if additional revenue exceeds additional processing cost.

Responsibility Accounting Framework

• Definition: A system of accounting that recognizes various responsibility centres and assigns revenues and costs to the individual held responsible.

• Assumptions:     * Managers are only charged with items they control.     * Managers must participate in budget goal-setting.     * Performance reports must contain significant info for the specific area.

• Classification of Responsibility Centres:     1. Cost Centre: Focused on accumulating and controlling costs.     2. Profit Centre: Financial performance measured as $\text{Revenue} - \text{Cost}$.     3. Revenue Centre: Responsible for generating sales volume; manager controls marketing expenses but not product costs.     4. Investment Centre: Measured by Return on Investment (ROI).

• Investment Metrics:     * $ROI = \frac{\text{Net Profit}}{\text{Investment}} \times 100$     * Residual Income (RI): $\text{RI} = \text{Divisional Profit} - (\text{Percent Capital Charge} \times \text{Divisional Investment})$.

Activity-Based Costing (ABC) Model

• Rationale: Traditional systems allocation was based purely on production volume (e.g., labour hours). ABC recognizes that overheads are driven by complexity and range of products, not just volume.

• ABC Process Flow: Tracing resources to Activities, then tracing activities to Products based on consumption.

• Cost Drivers: The factors that cause costs to be incurred (e.g., number of setups, number of inspections, number of purchase orders).

• Activity Levels:     1. Unit-level: Performed every time a unit is produced (e.g., direct power).     2. Batch-level: Performed for each batch (e.g., machine setup, material handling).     3. Product-level: Performed to support specific product types (e.g., engineering design, product marketing).     4. Facility-level: Sustains general manufacturing (e.g., plant security, factory management) - often treated as period costs.

• Implementation Steps:     1. Process Specification.     2. Identify activities (Unit, Batch, Product, Facility levels).     3. Identify Non-Value-Added (NVA) activities for elimination.     4. Create Cost Pools.     5. Identify specific Cost Drivers.     6. Calculate Cost Driver Rates: $\text{Rate} = \frac{\text{Total Overhead in Pool}}{\text{Total Driver Volume}}$.     7. Assign costs to units based on their actual driver usage.

Financial Illustrations

• Illustration 1 (Output and Efficiency):     * Base Data: Direct Materials ($50,000$), Direct Wages ($30,000$), Fixed Overhead ($15,000$), Variable Overhead ($10,000$).     * Conditions for 2018-19: $50\%$ more workers, efficiency drops $10\%$, fixed overhead increases $20\%$, materials cost drops $5\%$.     * Calculation of Output Change: Base ($100\%$) + New workers ($50\%$) = $150\%$. Less $10\%$ efficiency drop ($150 \times 0.10 = 15$) results in $135\%$ final output. Net increase = $35\%$.     * Budget Calculation:         * Materials: $50,000 + 35\% - 5\% \text{ price decline} = 64,125$.         * Wages: $30,000 + 50\% = 45,000$.         * Fixed OH: $15,000 + 20\% = 18,000$.         * Variable OH: $10,000 + 50\% = 15,000$.     * Total Budget: $142,125$.

• Illustration 2 (ABC Costing):     * A set of cost pools and volumes: Material procurement ($580,000$; $1000$ orders), Maintenance ($970,000$; $8400$ hours), Machinery ($720,000$; $24000$ machine hours).     * Cost Driver Rates:         * Procurement: $\frac{580,000}{1,000} = 580$ per order.         * Maintenance: $\frac{970,000}{8,400} = 115.48$ per hour.         * Machinery: $\frac{720,000}{24,000} = 30$ per hour.     * Application to Batch AX-15 (Example): If the batch used 26 orders and 1,800 machine hours, the overheads would be $26 \times 580 + 1,800 \times 30$.
