Generally Accepted Accounting Principles (GAAP)
QUICK ANSWER
Generally Accepted Accounting Principles are a standardized set of accounting rules, standards, and procedures used in the United States to ensure consistency, transparency, and comparability in financial reporting. They are established and maintained by the Financial Accounting Standards Board (FASB) and are required for publicly traded companies and widely adopted by private businesses as well.
In depth
GAAP covers a broad range of accounting topics including revenue recognition, balance sheet classification, materiality, and the matching principle. Its core objective is to ensure that financial statements prepared by different companies are consistent enough to be meaningfully compared by investors, lenders, and regulators. Key principles underpinning GAAP include the principle of regularity (following established rules), the principle of consistency (applying the same methods across periods), the principle of sincerity (presenting an honest and accurate picture), and the principle of continuity (assuming the business will continue operating).
For businesses seeking external investment, going public, or undergoing an audit, GAAP compliance is not optional. Investors and lenders rely on GAAP-compliant financials because they carry a level of credibility and standardization that non-GAAP figures do not. While private companies are not legally required to follow GAAP in the US, doing so signals financial maturity and makes due diligence processes considerably smoother. It is also worth noting that GAAP differs from IFRS, the international accounting standard used in over 140 countries, and companies operating across borders need to be aware of where these two frameworks diverge in their treatment of key accounting items.
