Mo. Rev. Stat. § 29.185: Conducting of audits, requirements.

When conducting an audit under this chapter, the audit objectives as defined in the standards established by the comptroller general of the United States shall determine the type of audit to be conducted which may include financial and performance audits. Neither the audit type nor the audit objectives shall be mutually exclusive. An audit may include either financial or performance audit objectives or one or more objectives from both types of audits. A performance audit may include one primary objective, such as economy and efficiency, or a combination of objectives, such as internal control and compliance.
