Correct. The SAS 70 audit has been out of existence since June 15, 2011. Many organizations are still being asked for SAS 70, frankly, due to the fact of its nearly 20-year existence and lack of education surrounding the change of the standard.
Since SAS 70 has been around nearly 20 years, its terminology seems stuck in the written agreements of many organizations that have long-term contractual obligations. Transitioning SAS 70 out of audit terminology is going to take an effort from the profession, as well as, publicity of the profession to make sure that these organizations understand SSAE 16, its replacement of SAS 70, and what it brings to the table to align it more with an assertion based report rather than a direct reporting on the controls.
