In 1995, the Board of Supervisors established the AOC based upon the recommendtion of a Blue Ribbon Comittee comprised of private sector industry leaders from Fortunate 500 Corporations based in Orange County.  As such, OC immediately established itself as the leader in applying corporate best practices to County governance.  In 2007, the OC AOC governance model was audited and found to be in full compliance with all significant and applicable best practices of the AICPA, IIA and GFOA standards.
