01-017-7 Me. Code R. § 76
Unless otherwise specified in the conditions, the money distribution in dashes shall be 50%, 25%, 12%, 8% and 5%. In early closing races, late closing races, or added money events, if there are less than five premium positions for which horses are placed, the remaining premium shall go to the race winner unless the conditions call for a different distribution. In overnight events if there are fewer than five starters the premium for the positions for which there are no horses placed must be retained by the track for future supplement of purses.
If there be any premium or premiums for which horses have started but were unable to finish, due to an accident or otherwise, all unoffending horses who did not finish will share equally in such premium or premiums.
