Lesson 1.3: Fundamental Principles and Accounting Assumptions

1. Underlying Accounting Assumptions

To build a reliable ledger, accountants rely on four foundational postulates:

Going Concern Assumption: The financial statements are prepared on the assumption that the entity is a going concern and will continue its operations for the foreseeable future (typically at least 12 months from the reporting date). If liquidation is imminent, this assumption fails, and statements must be prepared on a liquidation basis.
Monetary Unit Assumption: Economic activity is measured and recorded in a stable currency unit (e.g., USD, EUR). It assumes the currency’s purchasing power remains stable over time, ignoring the effects of hyperinflation unless specific inflation-adjustment standards are triggered.
Economic Entity Assumption: The economic activities of a business entity must be kept completely separate and distinct from the personal financial activities of its owners, partners, or shareholders.
Time Period (Periodicity) Assumption: The economic life of a business can be divided into artificial, distinct time periods (e.g., monthly, quarterly, or annually) to provide timely performance reports to users.

2. Measurement and Reporting Principles

Historical Cost Principle: Transactions are initially recorded at the original cash-equivalent cost paid to acquire the asset or incur the liability. This provides high verifiability but can sacrifice current relevance over time.
Fair Value Principle: The price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. IFRS relies more broadly on fair value revaluations than US GAAP.
Matching Principle (Expense Recognition): Expenses must be recognized in the income statement in the same accounting period as the related revenues they helped generate. This drives the cause-and-effect relationship between effort and reward.
Full Disclosure Principle: Entities must report all necessary information and financial facts that could reasonably influence the judgment of an informed user. This is achieved via inline disclosures and comprehensive accompanying footnotes.
