GAAP (Generally Accepted Accounting Principles) is the accounting standard used in the U.S., considered rules-based, while IFRS (International Financial Reporting Standards) is used in over 110 countries and is principles-based. The SEC is aiming to transition to IFRS by 2015, and both frameworks seek to provide relevant information to a wide range of stakeholders but differ in terms of definitions, inventory estimates, and qualitative characteristics. Under GAAP, the definition of an asset focuses on future economic benefits, while IFRS describes it as a resource generating future economic benefits.
