There exist inspections carried out in line with special audit engagements after which a special opinion, the content and procedure of which differs from general audit opinions, is issued.
In such cases the audit procedure is regulated by the Rule (standard) “Opinion of the auditing organisation on special audit engagements”’, approved by the Audit Commission under the President of the Russian Federation on 20 October 1999. (Minutes No.6).
An ad hoc audit may only be carried out upon an initiative, at any time, in volumes agreed upon in the Statement of Works.
