After nominees have been determined, final voting ballots are sent to NARAS voting members, who may then vote in the general fields and in no more than nine of the 30 fields. Members are encouraged, but not required, to vote only in their fields of expertise. Ballots are tabulated secretly by the major independent accounting firm Deloitte Touche Tohmatsu. Following the tabulation of votes the winners are announced at the Grammy Awards. The recording with the most votes in a category wins and it is possible to have a tie (in which case the two or more nominees who tie are all considered winners). Winners are presented with the Grammy Award and those who do not win are given a medal for their nomination.
