This text has been written so that it is current with all issues inherent in accounting and auditing practice, particularly in public accounting firms including coverage of the creation of the Public Companies Accounting Oversight Board, the passage of the Sarbanes-Oxley Act, and all of the major pronouncements issued by the AICPA. The text is also designed to provide flexibility for instructors; the twelve chapters focus on the auditing process while the eight modules provide additional topics that can be taught at the instructors' discretion without interrupting the flow of the text.
