The AICPA Auditing Standards Board has issued a Proposed SAS on Audit Evidence. The SAS is intended to modernize auditing standards to recognize new sources of information and evolving business technologies. Emerging technologies such as audit data analytics and blockchain are now used by financial statement preparers and by auditors alike. This evolution drives new challenges related to audit evidence and professional skepticism. The standard includes attributes and factors to be used in evaluating audit evidence. Feedback is due by September 18, 2019.
