The Office of Indian Gaming and Regulatory Compliance’s (OIGRC) Field Audit section is responsible for reviewing Tribal Class III gaming facility compliance with Compact provisions and Tribal minimum internal control standards. This is accomplished through the conduct of regular, onsite compliance and financial audits of these facilities.  Compliance audits are conducted approximately every 18 months and include gaming device testing, review of surveillance, cash handling and security procedures as well as table games operations (where applicable). Financial audits include a review of  financial documents and comparison to Tribal financial data previously submitted to the OIGRC for purposes of calculating Tribal net win and Tribal payments to the State of Wisconsin.
