The AIG consists of senior line supervisors from Basel member countries, who gather regularly to share best practices and develop ways to foster consistent application across national jurisdictions. Among its efforts is a series of case studies, in which home and host supervisors review how the banks under study plan to implement Basel II.
To date, a dozen case studies have been launched, and more are planned. Of course, the usefulness of each case study depends on how far along the subject bank is in its own Basel II implementation plan.
