In late December, ballots, and copies of the Reminder List of Eligible Releases are mailed to around 6,000 active members. For most categories, members from each of the branches vote to determine the nominees only in their respective categories (i.e. only directors vote for directors, writers for writers, actors for actors, etc.). In the special case of Best Picture, all voting members are eligible to select the nominees. In all major categories, a variant of the single transferable vote is used, with each member casting a ballot with up to five nominees (ten for Best Picture) ranked preferentially. In certain categories, including International Feature Film, Documentary and Animated Feature, nominees are selected by special screening committees made up of members from all branches.
