Accounting Principles: What They Are and How GAAP and IFRS Work

What Are Accounting Principles?

Accounting principles are the rules and guidelines that companies and other bodies must follow when reporting financial data. These rules make it easier to examine financial data by standardizing the terms and methods that accountants must use.

The International Financial Reporting Standards (IFRS) is the most widely used set of accounting principles, with adoption in 168 jurisdictions. The United States uses a separate set of accounting principles, known as generally accepted accounting principles (GAAP).

Understanding Accounting Principles

The ultimate goal of any set of accounting principles is to ensure that a company’s financial statements are complete, consistent, and comparable.

This makes it easier for investors to analyze and extract useful information from the company’s financial statements, including trend data over a period of time. It also facilitates the comparison of financial information across different companies.

Accounting principles also help mitigate accounting fraud by increasing transparency and allowing red flags to be identified.

Comparability

Comparability is the ability for financial statement users to review multiple companies’ financials side by side with the guarantee that accounting principles have been followed to the same set of standards.

Accounting information is not absolute or concrete, and standards are developed to minimize the negative effects of inconsistent data. Without these rules, comparing financial statements among companies would be extremely difficult, even within the same industry. Inconsistencies and errors also would be harder to spot.

What Are the Basic Accounting Principles?

Some of the most fundamental accounting principles include the following:

• Accrual principle
• Conservatism principle
• Consistency principle
• Cost principle
• Economic entity principle
• Full disclosure principle
• Going concern principle
• Matching principle
• Materiality principle
• Monetary unit principle
• Reliability principle
• Revenue recognition principle
• Time period principle

The most notable principles include the revenue recognition principle, matching principle, materiality principle, and consistency principle. Completeness is ensured by the materiality principle, as all material transactions should be accounted for in the financial statements. Consistency refers to a company’s use of accounting principles over time.

Generally Accepted Accounting Principles (GAAP)

Generally accepted accounting principles (GAAP) are uniform accounting principles for private companies and nonprofits in the U.S. These principles are largely set by the Financial Accounting Standards Board (FASB), an independent nonprofit organization whose members are chosen by the Financial Accounting Foundation.

A similar organization, the Governmental Accounting Standards Board (GASB), is responsible for setting the GAAP standards for local and state governments. A third body, the Federal Accounting Standards Advisory Board (FASAB), publishes the accounting principles for federal agencies.

Although privately held companies are not required to abide by GAAP, publicly traded companies must file GAAP-compliant financial statements to be listed on a stock exchange. Chief officers of publicly traded companies and their independent auditors must certify that the financial statements and related notes were prepared in accordance with GAAP.

Privately held companies and nonprofit organizations also may be required by lenders or investors to file GAAP-compliant financial statements. For example, annual audited GAAP financial statements are a common loan covenant required by most banking institutions. Therefore, most companies and organizations in the U.S. comply with GAAP, even though it is not a legal requirement.

International Financial Reporting Standards (IFRS)

The International Accounting Standards Board (IASB) issues International Financial Reporting Standards (IFRS). These standards are used in approximately 168 jurisdictions, including those in the European Union (EU).

The Securities and Exchange Commission (SEC), the U.S. government agency responsible for protecting investors and maintaining order in the securities markets, has expressed interest in transitioning to IFRS. However, because of the differences between the two standards, the U.S. is unlikely to switch in the foreseeable future.

However, the FASB and the IASB continue to work together to issue similar regulations on certain topics as accounting issues arise.

Since accounting principles differ around the world, investors should take caution when comparing the financial statements of companies from different countries. The issue of differing accounting principles is less of a concern in more mature markets. Still, caution should be used, as there is still leeway for number distortion under many sets of accounting principles.

The Bottom Line

Accounting principles are rules and guidelines that companies must abide by when reporting financial data. Which method a company chooses at the outset—or changes to at a later date—must make sound financial sense.

Whether it’s GAAP in the U.S. or IFRS elsewhere, the overarching goal of these principles is to boost transparency and make it easier for investors to compare the financial statements of different companies.

Without these rules and standards, publicly traded companies would likely present their financial information in a way that inflates their numbers and makes their trading performance look better than it actually was. If companies were able to pick and choose what information to disclose, it would be extremely unhelpful for investors.
