The exemption was granted on the basis of: The unique level of knowledge that Mercer possessed of Health’s requirements and systems, and the risks and delays that would be anticipated to arise from onboarding an alternative CUA contractor The urgency of having the actuarial services completed to enable WA Health to meet critical upcoming timelines and milestones
