In the 2014 Triennial Surveillance Review, the Board approved the shift from a three-year to a five-year cycle for Comprehensive Surveillance Reviews (CSRs) and requested a smaller-scale interim report after 2½-3 years to assess implementation, identify emerging pressure points, and help shape the subsequent CSR. In 2024, the Board endorsed Management’s proposal to cancel the planned 2025 Interim Surveillance Review, to focus staff’s efforts on completing the CSR by May 2026, five years after the 2021 CSR. This Board paper provides the background on this decision and explains how related risks are mitigated.
