The calcutta is an optional event that increases audience participation. At the beginning of the rodeo teams enter the arena during the grand entry, and immediately following spectators are able to "place bids" through auction to purchase a team for the day, highest bid wins that team.
All monies generated in the calcutta are grouped. 10% is taken off the top, and goes towards the Host Committee; an additional 10% goes towards the MRRA. Person(s) whom purchased the teams that ended the day with the top 4 placing's of points win the remaining money. The remaining 80% is paid out at 40% for a team placing first, 30% for a second placing team, 20% for a third place, and 10% to the fourth place.
