If the problems have not been resolved in a reasonable time, the project must be cancelled. Unspent funds defined as a target resource assignment from the core that result from a cancelled project may be reprogrammed, considering the outstanding obligations of the cancelled project. Third-party contributions may be reprogrammed subject to approval by the donor (unspent funds must be returned to vertical funds such as the GEF or GCF). The implementing partner proceeds with the steps required for financial completion as described in project closure. If cancellation means significant changes in the approved country programme document, an amendment may be needed.
