   • The Business Entity Concept establishes that a business is treated as a separate entity from its owners for accounting purposes.
   • The Money Measurement Concept requires that only transactions quantifiable in monetary terms are recorded in the accounting system.
   • The Going Concern Concept presumes that a business will continue its operations for an indefinite period, without intent of liquidation.
   • The Accrual Concept dictates that revenues and expenses are recognized when they are earned or incurred, irrespective of cash flow.
   • The Dual Aspect Concept (or Duality Principle) states that every financial transaction affects at least two accounts, with equal debits and credits, maintaining the accounting equation.
