Generally Accepted Accounting Principles:
US GAAP refers to the standard framework of guidelines for financial accounting used in the United States; generally known as Accounting Standards. GAAP includes the standards, conventions, and rules accountants follow in recording and summarizing , and in the preparation of financial statements.
The rules and procedures for reporting under GAAP are complex and have developed over a long period of time. Currently there are more than 150 "pronouncements" as to how to account for different types of transactions, ranging from how to report regular income from the sale of goods, and its related inventory values, to accounting for incentive stock option distributions. By using consistent principles, all companies reporting under GAAP report these transactions on their financial statements in a consistent manner.
The various rules and pronouncements come from the Financial Accounting Standards Board (FASB) which is a non-profit organization that the accounting profession has created to promulgate the rules of GAAP reporting and to amend the rules of GAAP reporting as occasion requires. The pronouncements come as Statements of the Financial Accounting Standards (SFAS).
