Concessions were introduced in 2014 in a bid to help balance the field and provide a greater competitive platform for prospective manufacturers, which helped bring Suzuki, Aprilia and KTM to the grid between 2015 and 2017.
Those who ran under concessions received a number of benefits over non-concession manufacturers, who at the time were Honda and Yamaha, which included unrestricted in-season testing, a bigger engine allocation and unlimited engine development.
To be considered for concessions when they were introduced in 2014, a manufacturer either had to have been new to the grid or had gone without a dry weather race win the previous year.
Concessions were stripped from a manufacturer after it had accumulated six concession points in a season, which were determined on results: three for a win, two for a second and one for third.
Aprilia was the last manufacturer to lose concessions, doing so last year, with all manufacturers in 2023 running to the same rules.
Under the current rules framework, the only regulatory alternative for someone to have those concessions again would be for none of its riders to score a single podium in the Sunday races - something Honda and Yamaha has already achieved with Alex Rins' Americas Grand Prix victory and Fabio Quartararo's third in that race respectively.
Yamaha, who has only two bikes on the grid in 2023, sits bottom of the constructors' table, with Honda - who has four representatives - just seven points clear in fourth.
