3. Historical Cost Principle: This principle requires that a business record assets at their original cost.
4. Objectivity Principle: This principle requires that a business base its financial statements on objective evidence.
5. Stable Monetary Unit Concept /Unit of Measurement: This principle assumes that the value of money is stable over time and that financial statements should be presented in a consistent unit of measurement.
6. The Periodicity Concept /Accounting Period Concept: This principle assumes that a business can be divided into artificial time periods for the purpose of preparing financial statements.
7. The Matching Principle: This principle requires that a business match expenses with the revenue they helped generate.

9. Adequate Disclosure Principle: This principle requires that a business disclose all relevant information in its financial statements.
10. The Consistency Principle: This principle requires that a business use the same accounting methods from one period to the next.
