What is U.S. GAAP? Why Must Companies Comply?

When accessing the U.S. capital market, companies must adhere to the Generally Accepted Accounting Principles (U.S. GAAP) to ensure transparency and standardization of financial information. U.S. GAAP is established by the Financial Accounting Standards Board (FASB) and recognized by the U.S. Securities and Exchange Commission (SEC), making it a fundamental requirement for listing on NASDAQ or the New York Stock Exchange (NYSE). For companies entering the U.S. market, key aspects such as asset measurement, revenue recognition, and financial statement preparation must comply with U.S. GAAP.

Differences Between U.S. GAAP and IFRS

In contrast, International Financial Reporting Standards (IFRS) are adopted by more countries. However, the U.S., home to the world’s largest capital market, continues to follow U.S. GAAP. The key differences include:

1. Rules-Based vs. Principles-Based Approach – U.S. GAAP follows a rules-based approach with detailed accounting guidelines, whereas IFRS adopts a principles-based framework that allows for more judgment based on business substance.
2. Inventory Valuation – U.S. GAAP permits the Last-In, First-Out (LIFO) method, while IFRS only allows First-In, First-Out (FIFO) and the weighted average cost method.
3. Revenue Recognition – U.S. GAAP follows the ASC 606 standard, requiring revenue to be recognized when specific contractual obligations are met. IFRS allows a more gradual recognition approach.
4. Asset Impairment – U.S. GAAP requires a four-step impairment test, whereas IFRS employs a single-step calculation.
5. R&D Cost Treatment – Under U.S. GAAP, research and development expenses must be expensed immediately, whereas IFRS may allow them to be capitalized as assets.

Why Companies Must Comply with U.S. GAAP

1. Mandatory for U.S. Stock Exchanges – Companies seeking to list on NASDAQ and NYSE must submit U.S. GAAP-compliant financial statements to pass SEC review.
2. Enhances Investor Confidence – Standardized asset measurement and revenue recognition rules enable investors to compare financial performance across companies more easily.
3. Reduces Audit and Regulatory Risks – Failure to comply with U.S. GAAP can result in SEC investigations, financial restatements, or penalties.
4. Increases IPO Success Rate – Companies that prepare U.S. GAAP-compliant financial statements can accelerate their IPO approval process.
