The Fifth Edition presents current issues and adapts auditing approaches to business and economic complexities, focusing on the analysis of business risk and identifying fraud in the new auditing environment. Due to recent accounting, governance, and auditing scandals, and the overhaul of the regulatory environment in auditing, Rittenberg Fifth Edition contains the most comprehensive and up-to-date look at audit regulation, concepts, and practices while also adapting traditional techniques and procedures to a technological, systems-oriented environment. ACL audit software is provided with every new copy, and its use is integrated into text and end-of-chapter problems. An ACL Case Appendix provides practice in audit techniques. Audit case modules using Biltrite Bicycles, Inc., are tied to related chapters.
