The Australian Reinsurance Pool Corporation has made changes that will see two members of its senior executive team leave.

The team is now comprised of CEO Chris Wallace, COO Michaela Flanagan, CFO John Park and Chief Underwriting Officer Mike Pennell.

GM Governance Risk and Compliance Joshua Everson and GM Insurance Audit and Claims Michael Stallworthy will leave the terrorism reinsurance scheme administrator.

Dr Wallace says the changes will streamline the corporation and increase collaboration.
