The Event Review Time indicates how much time, beyond the close of the event, that the event host and sourcing partner reserve the right to re-open the event. Also known as the “validation period”, this time is used to review all the details of the event to ensure there were no technical difficulties and /or that the system accepted all quotes, as appropriate. The event review time requires each participant to be available, via telephone, during the event review time. If a participant has not heard from the sourcing partner within this time, then the event is considered closed. The results will be reviewed by the host, who will decide on the award of business.
