For over 40 years, Statement on Auditing Standards No. 70 (SAS 70) and its predecessors have been the U.S. standard for reporting on controls at service organizations.

The International Auditing and Assurance Standards Board (IAASB) and the Auditing Standards Board (ASB) in the United States have developed new standards for reporting on controls at a service organization, with a truly global constituency in mind.
