Upon completion of the count in the polling places on Oct. 10, procedures called for the presiding officer to hand over the packed tamper- evident envelopes, sealed ballot boxes, and other sensitive materials to the NEC election supervisor responsible for the district. The election supervisor and security personnel were to transport the material to the county-level magistrate’s office for tallying at the county level. Tally centers with a large number of precincts in their area had multiple tally teams. Results were entered in a database and periodically transmitted to the national tally center at the NEC in Monrovia  .
