Audit Committee

Independent Audit Committee

What We Do

The independent Audit Committee was created in 2006 when Denver voters voted to change the City Charter in order to streamline the city’s financial structure. Auditor O’Brien is the chairman of the independent Audit Committee, which meets monthly. The other six members of the committee are appointed to four-year terms. Members are appointed based on education or experience in accounting, auditing, financial management, or related fields. The primary responsibility of the Audit Committee is to commission an annual independent external audit of the city’s finances. The Audit Committee receives the results of audits, assessments, and examinations performed or commissioned by the Auditor’s Office, and the results of the annual external audits.
