IFRS vs. GAAP:

An Introduction for Internal Auditors

Training Introduction

Background

With businesses increasingly operating across borders, internal auditors are more frequently encountering financial reporting prepared under different accounting frameworks—primarily International Financial Reporting Standards (IFRS) and Generally Accepted Accounting Principles (GAAP) (typically referring to U.S. GAAP). While both aim to present a true and fair view of financial performance, key differences in recognition, measurement, and disclosure can affect risk assessments, internal controls, and audit procedures.

Understanding these differences is essential for internal auditors who must evaluate financial reporting risks, audit internal controls over financial reporting, and communicate effectively with finance, external auditors, and audit committees.
