For the auditing of the administration and finances of the Helsinki City, the City Council chooses an Auditor on the basis of competitive bidding by the proposition of the Audit Committee. The Auditor must be an audit corporation approved by the Board of Chartered Public Finance Auditing, so called a CPFA corporation. The Auditor provides the Council with a report on each financial year presenting the results of their auditing. The report must also state whether the financial statements are acceptable, and whether the individual member of the institution and the leading holder of the office of the designated institution may be granted release from liability. On the 29th of April 2009, the City Council chose Ernst & Young Julkispalvelut Oy to audit the administration and finances of the Helsinki City during the years 2009 to 2012.
