What are the main accounting principles (Historical Cost, Matching, Revenue Recognition, etc.)?

The main accounting principles guide how transactions are recorded and reported. These include Historical Cost Principle, Revenue Recognition Principle, Matching Principle, and Full Disclosure Principle.

Main Accounting Principles

Accounting principles are rules that guide how financial transactions are recorded and reported. They ensure consistency and comparability in financial statements.

Four Key Principles:

Historical Cost Principle
Revenue Recognition Principle
Matching Principle
Full Disclosure Principle

Detailed Explanation of Each Principle

1. Historical Cost Principle

Definition: Record assets at their original purchase cost.

Example: Buy equipment for $50,000 → Record at $50,000, not current market value
Exception: Some assets revalued (like investment property under IFRS)
Advantage: Objective and verifiable

2. Revenue Recognition Principle

Definition: Recognize revenue when earned and realizable.

Criteria: Goods delivered/services performed, price fixed, collectible
Example: Recognize revenue when product shipped, not when cash received
Under IFRS 15: Five-step model for revenue recognition

3. Matching Principle

Definition: Match expenses with related revenues in the same period.

Example: Match cost of goods sold with sales revenue
Application: Use accrual accounting (not cash basis)
Purpose: Accurate profit measurement for each period

4. Full Disclosure Principle

Definition: Disclose all relevant information in financial statements.

Example: Notes explaining accounting policies, contingent liabilities
Requirement: Information that affects user decisions must be disclosed
Includes: Accounting policies, related party transactions, subsequent events

Other Important Principles

5. Materiality Principle

Include only significant information that could affect decisions.

Example: $10 error in million-dollar company not material
Judgment: Based on size and nature of item

6. Conservatism (Prudence) Principle

When in doubt, choose method that understates assets/income rather than overstates.

Example: Record potential losses immediately, but not potential gains
Application: Lower of cost or market for inventory

7. Consistency Principle

Use same accounting methods from period to period.

Purpose: Comparability between periods
If change: Must disclose and justify

8. Objectivity Principle

Accounting information should be based on objective evidence.

Example: Use invoices, contracts, bank statements
Avoid: Estimates based on personal opinions

Relationship with Assumptions:

Principles tell HOW to account, while Assumptions provide foundation for accounting.

Practical Examples:

Transaction	Principle Applied	Accounting Treatment
Buy building for $500,000	Historical Cost	Record at $500,000
Sell goods on credit	Revenue Recognition	Record revenue when sold, not when cash received
Pay sales commission	Matching	Record as expense in same period as related sale
Pending lawsuit	Full Disclosure	Disclose in notes to financial statements

Important Notes:

Principles provide framework for preparing financial statements
Different from accounting standards (GAAP/IFRS) which are more detailed rules
Must apply professional judgment when principles conflict
Principles evolve over time with business changes
Auditors ensure principles are properly applied
