Formula One Management (FOM) is the main operating company of the group, and controls the broadcasting, organisation and promotional rights of Formula One. The company makes the televised feeds of all Grand Prix sessions, which are then supplied through the Eurovision satellites network (EBU) to broadcasters who provide commentary and distribute the feed in the authorised region(s) of said broadcasters. The production arm of FOM is based at Biggin Hill Airport, Kent, for easy travel of the equipment needed to broadcast the race. Financially, FOM provides partial investment for new tracks and teams, to allow them to establish themselves in the sport and grow Formula One's presence in new markets. The season calendar for the championship is structured by FOM, with the WMSC having oversight. Payments to the teams are determined by the Concorde Agreement, which gives the teams 50% of the television money in Constructors' Championship order, and awards a prize fund to teams based upon their results, which is drawn from the fees Grand Prix promoters pay for staging the race. The logistics of moving equipment and personnel from each race is also handled by FOM, which provides the teams with a set amount of transport for the races outside of Europe.
