On 27 March 2006, the five Grand Prix Manufacturers Association-backed teams - BMW Sauber, Renault, Honda, McLaren and Toyota - submitted their applications for the 2008 season, agreeing to stay in the sport until 2012. On 14 May 2006, the five GPMA-backed teams signed a memorandum of understanding with the commercial rightsholders (CVC/Ecclestone) which formed the basis of the next Concorde Agreement. As such, a full Concorde Agreement was not in place for the season, with the Memorandum, extensions and agreements with the other individual teams acting as a stop-gap solution.
