Due to the growing complexity in the fields of accounting and auditing, the U.S. CPA AUD exam will now test new topics, while also removing a few topics from the exam. The topics removed include opening balances, the auditing of derivatives, and the communication of "other matters" with management and those charged with governance. Additionally, the topics of single statements, alerts that restrict the use of written communication, and letters for underwriters and filings with the SEC will be removed.
