US GAAP Principles Explained: Key Concepts for Financial Reporting
(2025 Update)
Singapore-based In finance and accounting, consistency and comparability are essential for businesses and investors alike. To ensure uniformity in financial reporting, the United States has adopted Generally Accepted Accounting Principles (US GAAP), which provide a set of standards and guidelines for preparing financial statements.
Understanding the core principles of US GAAP (Generally Accepted Accounting Principles) is essential for businesses involved in cross-border operations, financial audits, or preparing for US listings. Whether you’re a Singaporean company with American investors or a subsidiary of a US-based multinational, adhering to US GAAP ensures transparency, consistency, and compliance.
This article explores the key principles that underpin US GAAP and their importance in financial reporting and decision-making. Additionally, we will discuss the role of audit firms in Singapore in upholding these principles, especially for multinational corporations operating in the region. We explain what US GAAP is, who needs to follow it, and the fundamental accounting principles that guide US-standard financial reporting.
What is US GAAP?
US GAAP is a set of accounting standards, conventions, and rules that public companies in the United States are required to follow when preparing their financial statements. These principles are issued and updated by the Financial Accounting Standards Board (FASB).
US GAAP is also recognised by the U.S. Securities and Exchange Commission (SEC) as the required standard for listed companies. Private companies may also follow US GAAP for consistency or financing purposes.
Key Principles of US GAAP
Principle of Regularity
This principle requires that a company follows established accounting principles consistently to ensure comparability between its financial statements and those of other companies.
Consistency Principle
Under this principle, a company should use the same accounting methods and policies for similar transactions and events over time. Consistency enhances the reliability and relevance of financial information.
Principle of Permanence of Methods
A company should not change its accounting methods frequently. Changes should be made only when necessary to improve the presentation of financial information and should be disclosed in the financial statements.
Principle of Non-Compensation
This principle discourages offsetting different assets, liabilities, revenues, and expenses in the financial statements. Each item should be presented separately to provide clarity and transparency.
Principle of Materiality
Materiality refers to the significance or relevance of information. US GAAP requires that financial information is disclosed if its omission or misstatement could influence the decisions of financial statement users.
Principle of Continuity
This principle assumes that a business will continue its operations for the foreseeable future. Financial statements are prepared on a going concern basis, unless there is substantial evidence to the contrary.
Principle of Utmost Good Faith
This principle emphasizes the need for full disclosure of all material information in the financial statements. Companies should provide all relevant information to prevent users from being misled.
Principle of Periodicity
This principle mandates that a company divides its economic activities into time periods (usually fiscal years). Financial statements should be prepared at regular intervals to provide useful information for decision-making.
Revenue Recognition Principle
Revenue is recognised when it is earned and realisable, not when cash is received. This supports the accrual basis of accounting.
Example: A software company bills a client in December but receives payment in January. Under GAAP, the revenue is recorded in December.
Historical Cost Principle
Assets are reported based on their original purchase cost, not current market value. This ensures consistency and objectivity.
Example: A building purchased for RM2 million in 2010 remains recorded at that value, even if its market price increases.
Matching Principle
Expenses must be recorded in the same accounting period as the revenues they help generate.
Example: The cost of goods sold (COGS) is matched with the revenue from product sales in the same quarter.
Principle of Sincerity
The principle of sincerity dictates that financial statements should reflect the company’s financial position and transactions faithfully. Information should not be manipulated or biased to mislead users.
Full Disclosure Principle
All relevant financial information that could influence decision-making must be disclosed in financial statements, often in the footnotes.
Example: Pending lawsuits, lease obligations, or debt covenants must be disclosed.
Importance of US GAAP Principles
The key principles of US GAAP are essential for several reasons:
Transparency and Accuracy
US GAAP principles emphasize the importance of transparency and accuracy in financial reporting. This helps prevent fraudulent activities and misleading financial statements.
Consistency and Comparability
These principles ensure that financial statements are prepared in a consistent manner, making it easier to compare the financial performance and position of different companies. This is particularly important for investors and analysts.
Regulatory Compliance
Adhering to US GAAP is necessary for companies listed on US stock exchanges. Compliance with these principles ensures that companies meet regulatory requirements, reducing the risk of penalties and legal issues.
Stakeholder Confidence
When companies adhere to US GAAP principles, they build trust and confidence among investors, lenders, and other stakeholders. This, in turn, makes it easier for companies to raise capital and attract investment.
Global Recognition
US GAAP principles are recognized internationally and followed by many multinational corporations. This global recognition simplifies financial reporting for companies with operations in multiple countries.
Why It Matters for Singaporean Companies
Many Singapore-based companies operate as regional hubs, subsidiaries, or suppliers to US-based corporations. If you’re involved in:
- Group reporting to a US HQ
- Cross-border mergers & acquisitions
- Fundraising with American investors
- SEC regulatory preparation for IPOs
For local businesses, it’s also important to understand how GAAP compares with Singapore Financial Reporting Standards (SFRS) and IFRS when aligning reports across jurisdictions.
The Role of Audit Firms in Singapore
For multinational corporations operating in Singapore, adherence to US GAAP principles is often crucial, as they might need to consolidate financial statements prepared in accordance with these principles. Audit firms in Singapore play a pivotal role in ensuring compliance with US GAAP for these businesses. Here’s how they contribute:
International Expertise
Many audit firms in Singapore have teams of experts who are well-versed in both US GAAP and international financial reporting standards. This expertise is invaluable for businesses preparing financial statements according to US GAAP.
Auditing US GAAP Financial Statements
Audit firms in Singapore audit the financial statements prepared by multinational corporations to ensure that they comply with US GAAP. This includes verifying the application of US GAAP principles and assessing the accuracy of the financial information.
Compliance Assurance
Audit firms provide assurance services to confirm that the financial statements comply with US GAAP, reducing the risk of misstatements and discrepancies.
Risk Mitigation
By conducting thorough audits, audit firms help businesses identify potential issues and risks related to US GAAP compliance. This allows companies to address and rectify issues before they become significant problems.
Regulatory Support
Audit firms assist businesses in navigating the complex regulatory environment related to US GAAP compliance, ensuring that they meet all reporting and disclosure requirements.
Who Should Understand US GAAP?
While US GAAP is required for American public companies, its relevance extends globally:
Singapore subsidiaries of US-listed companies must often report using US GAAP.
Businesses planning to raise capital or list in the US must prepare GAAP-compliant reports.
Audit and tax advisors must understand both GAAP and local standards (e.g., Singapore Financial Reporting Standards SFRS and IFRS in Singapore) to support clients effectively.
Latest US GAAP Updates (2025)

Why Singapore Companies Should Understand US GAAP
In Singapore, companies typically prepare financial statements using Singapore Financial Reporting Standards (SFRS), which are closely aligned with International Financial Reporting Standards (IFRS). These standards are governed by the Accounting and Corporate Regulatory Authority (ACRA) and are widely adopted for statutory compliance and reporting purposes.
However, some Singapore-based businesses—particularly those with US operations, US-based investors, or seeking a foreign listing on the SGX—may also need to prepare financial reports in accordance with United States Generally Accepted Accounting Principles (US GAAP).
Understanding US GAAP is essential if your business:
Is a subsidiary of a US-listed company
Has US-based stakeholders requesting US GAAP reports
Is exploring US capital markets or cross-border mergers and acquisitions
Operates in dual-reporting environments (SFRS + US GAAP)
By aligning with US GAAP, companies can increase transparency, support investor confidence, and meet regulatory expectations for global expansion.
When Is US GAAP Applicable to Singapore Businesses?
Most local SMEs and private companies in Singapore are not required to use US GAAP. However, US GAAP reporting may apply in the following cases:
Singapore subsidiaries of US multinational companies
These entities may need to report in US GAAP for consolidation purposes.Dual listings or foreign issuers on SGX
SGX allows foreign companies to prepare accounts in US GAAP if approved.M&A or fundraising with US investors
US venture capitalists or private equity firms may require US GAAP financial statements as part of due diligence.
In such cases, partnering with a professional accounting firm experienced in cross-border reporting ensures your financial statements comply with both US and Singapore standards.
US GAAP vs. IFRS: Key Differences
While US GAAP is the official standard in the US, many countries follow International Financial Reporting Standards (IFRS). Here’s how they differ:

Understanding these differences is crucial, especially when preparing consolidated group accounts, reconciling financials, or preparing investor reports for US-based stakeholders.
Local Audit Considerations
In Singapore, financial statements must comply with SFRS for statutory submission to ACRA and IRAS. However, where US GAAP statements are required for group consolidation or investor reporting, your external auditor may perform additional reconciliations or prepare a US GAAP conversion report.

For multinational corporations operating in Singapore, adherence to US GAAP may be essential, and audit firms in Singapore play a significant role in ensuring compliance and mitigating risks.
Ultimately, the key principles of US GAAP contribute to a more robust and reliable financial reporting environment, benefiting companies, investors, and the broader financial community.
Frequently Asked Questions (FAQ)
US GAAP is updated by the FASB through Accounting Standards Updates (ASUs). Regular updates ensure alignment with evolving financial needs.
Yes. Companies operating in multiple countries may prepare dual reports to comply with both US GAAP and IFRS requirements.
No. While public companies are mandated to follow GAAP, many private companies and foreign subsidiaries choose to follow it for investor transparency or audit readiness.
Yes — but only in a specific context. A Singapore subsidiary may prepare its statutory financial statements under SFRS (or SFRS(I) where applicable) for local filing with Accounting & Corporate Regulatory Authority (ACRA) and for Singapore tax purposes. For group consolidation purposes, if the parent entity (which may be in the US or another jurisdiction) uses US GAAP, the subsidiary’s accounts may need to be adjusted or converted to US GAAP. As noted in your article, “[In Singapore] companies must comply with SFRS … however, where US GAAP statements are required for group consolidation or investor reporting, your external auditor may perform additional reconciliations or prepare a US GAAP conversion report.”
In other words:
The subsidiary’s primary local reporting framework remains SFRS unless it is voluntarily adopting US GAAP.
The parent group may consolidate the subsidiary by converting its result to US GAAP-basis if the group financial statements are under US GAAP.
This involves reconciliation differences (e.g., measurement/timing differences, disclosure differences) between SFRS and US GAAP.
Thus, the subsidiary cannot simply “report under US GAAP instead of SFRS” for its Singapore statutory returns without meeting any applicable local regulatory or auditor requirements.
Generally no. Companies with a primary listing on the Singapore Exchange (SGX) must use SFRS(I). Only foreign-incorporated issuers with a secondary listing may continue reporting under US GAAP or IFRS, subject to SGX approval.
Key differences include:
- Framework: US GAAP is rules-based, while SFRS is principles-based.
- Inventory: LIFO is allowed under US GAAP but prohibited under SFRS.
- Development costs: Expensed under US GAAP; may be capitalised under SFRS.
- Revaluation: SFRS allows some asset revaluation; US GAAP generally does not.
These distinctions affect reported profit, equity, and disclosures for multinational groups.
Tax filings to IRAS must still follow SFRS-based accounts. US GAAP financials can be used for group or investor reporting but must be reconciled to SFRS for local audit and compliance. Auditors in Singapore typically issue opinions on SFRS-compliant statements, not pure US GAAP reports.
