In the United States, as well as in other countries practicing under the English common law system, the government does not set accounting standards, in the belief that the private sector has better knowledge and resources. The GAAP is not written in law, although the U.S. Securities and Exchange Commission (SEC) requires that it be followed in financial reporting by publicly traded companies.

Basic objectives

Financial reporting should provide information that is:

• useful to present and potential investors and creditors and other users in making rational investment, credit, and other financial decisions.
• helpful to present and potential investors and creditors and other users in assessing the amounts, timing, and uncertainty of prospective cash receipts.
• about economic resources, the claims to those resources, and the changes in them.

Fundamental qualities

To be useful and helpful to users, financial statements must be:

• Relevant: relevant information makes a difference in a decision. It also helps users make predictions about past, present and future events (it has predictive value). Relevant information helps users confirm or correct prior expectations (it has feedback value). It must also be available on time, that is before decisions are made.
• Reliable: reliable information is verifiable (when independent auditors using the same methods get similar results), neutral (free from bias), and demonstrate representational faithfulness (what really happened or existed).
• Comparable: information must be measured and reported in a similar manner for different enterprises (allows financial statements to be compared between different companies).
• Consistent: the same accounting methods should be applied from period to period and all changes in methods should be well explained and justified (allows financial statements of the same company to be compared between different periods).

Basic concepts

To achieve basic objectives and implement fundamental qualities GAAP has four basic assumptions, four basic principles, and four basic constraints.

Assumptions

• Economic Entity Assumption assumes that the business is separate from its owners or other businesses. Revenues and expenses should be kept separate from personal expenses. This applies even for partnerships and sole proprietorships. The entity concept does not necessarily refer to a legal entity.
• Going Concern Assumption assumes that the business will be in operation for a long time. This validates the methods of asset capitalization, depreciation, and amortization. Only when liquidation is certain is this assumption not applicable.
• Monetary Unit Assumption assumes a stable currency is going to be the unit of record. The FASB accepts the nominal value of the US Dollar as the monetary unit of record (unadjusted for inflation).
• Periodicity Assumption assumes that the business operations can be recorded and separated into different periods (most common periods are months, quarters and years). This is required for comparison between present and past performance.

Principles

• The historical cost principle requires companies to account and report based on acquisition costs rather than fair market value for most assets and liabilities. This principle provides information that is reliable (removing opportunity to provide subjective and potentially biased market values), but not very relevant. Thus there is a trend to use fair values. Most debts and securities are now reported at market values.
• The revenue recognition principle requires companies to record when revenue is (1) realized or realizable and (2) earned, not when cash is received. This way of accounting is called accrual basis accounting.
• The matching principle. Expenses have to be matched with revenues as long as it is reasonable to do so. Expenses are recognized not when the work is performed, or when a product is produced, but when the work or the product actually makes its contribution to revenue. Only if no connection with revenue can be established, cost can be charged as expenses to the current period (e.g. office salaries and other administrative expenses). This principle allows greater evaluation of actual profitability and performance (shows how much was spent to earn revenue). Depreciation and Cost of Goods Sold are good examples of application of this principle.
• The full disclosure principle. Amount and kinds of information disclosed should be decided based on trade-off analysis as a larger amount of information costs more to prepare and use. Information disclosed should be enough to make a judgment while keeping costs reasonable. Information is presented in the main body of financial statements, in the notes or as supplementary information.

Constraints

• Cost-benefit relationship states that the benefit of providing the financial information should also be weighed against the cost of providing it.
• Materiality states that the significance of an item should be considered when it is reported. An item is considered significant when it would affect the decision of a reasonable individual.
• Industry practices states that accounting procedures should follow industry practices.
• Conservatism states that when choosing between two solutions, the one that will be least likely to overstate assets and income should be picked.
