Cost Accounting Principles and Reporting Standards

Cost Classification and Management Accounting Reports

Understanding Cost Classification

Item 15: Cost Behavior

Semi-Fixed Costs: In practice, it is unlikely that fixed costs remain constant for all levels of activity. Sometimes they grow in stages, in which case they are referred to as semi-fixed costs. They remain constant over a range of output, but then experience a substantial alteration to meet a production volume of another scale range. Variables change with the volume of activity, but discontinuously.

Mixed (Semi-Variable) Costs: These costs contain both a fixed and a variable component. Separating its two components is often difficult in practice. Examples of semi-variable costs include maintenance, power, and telephone expenses.

Key Features of Management Accounting Reports

Management accounting reports differ significantly from financial accounting reports in several key aspects:

• Regulatory Compliance: Management accounting information does not need to comply with external obligations and legal requirements.
• Information Principles: The criteria to ensure the relevance and reliability of internal information must be founded on principles that may differ from those established by Generally Accepted Accounting Principles (GAAP).
• Timeliness and Forward-Looking Information: Timeliness and projected forward-looking information are two important features of management accounting reports. Accurate management information is crucial for making decisions quickly.
• Information Segmentation: While financial accounting reports refer to the company as a whole, management accounting produces analytical information, focusing on specific parts of the organization such as products, activities, geographical areas, departments, or clients.
• Frequency: The frequency of reports is determined by the specific needs of the decision-making process, including planning, execution, and control.

As is clear from the above features, reports prepared by Management Accounting rely almost exclusively on the peculiarities of each decision unit within an organization, making it difficult to establish standardized formats like those in Financial Accounting.

However, such standardization would be justified if it impacts the design of accounting schemes, especially concerning information passed to Financial Accounting.

Proposed Management Accounting Report Models

Among various models, the SASA proposed the following in Document No. 3 of the 'Principles of Management Accounting' series:

• Reports on costs of factors
• Reports on classification of factors
• Reports on cost centers and cost flows
• Reports on the cost structure of products and services
• Reports on variances
• Reports on margins and results

Example: Cost of Goods Sold Calculation

Initial Raw Material Stocks
+ Purchases of Raw Materials
- Ending Raw Material Stocks
= Consumption of Raw Materials

Consumption of Raw Materials
+ Direct Labor Cost
= Direct or Prime Cost

Direct or Prime Cost
+ Indirect Production Costs (Manufacturing Overhead, Supplies, Maintenance, Depreciation)
= Industrial Cost (or Cost of Initial Production)

Industrial Cost (or Cost of Initial Production)
+ Initial Work-in-Process Inventory
- Ending Work-in-Process Inventory
= Cost of Goods Manufactured

Cost of Goods Manufactured
+ Initial Finished Goods Inventory
- Ending Finished Goods Inventory
= Cost of Goods Sold
