The Audit Bureau has a statutory responsibility to perform a financial audit of the Employees’ Retirement System of the County of Milwaukee (County ERS), and a financial audit of the Employes’ Retirement System of the City of Milwaukee (City ERS). These audits include providing our opinion on the financial statements and related notes of these retirement systems under the requirements of Governmental Accounting Standards Board (GASB) Statement Number 67, Financial Reporting for Pensions.  In addition, for the City ERS, the audit includes providing an opinion on the related schedule of collective pension amounts prepared to provide information needed by employers, under GASB Statement Number 68, Accounting and Reporting for Pensions. To provide sufficient and appropriate audit evidence to support our audit opinions, the Audit Bureau contracts with an actuary to ensure the accuracy of the amounts calculated by each entity’s consulting actuary that are included in these financial reports.
