This document discusses theories of minimum and maximum collusion in the context of corporate fraud. It defines collusion as an agreement between two or more people to commit a dishonest act. There are two types of collusion: minimum collusion provides necessary opportunities, resources or skills to commit fraud, while maximum collusion aims to share benefits of low-skill frauds among many people. The nature and level of collusion varies depending on the type of fraud and skills required, ranging from passive awareness to committed participation in the fraud.
