Write a question about the following article: The Top 14 salary cap was set at 9.5 million for 2012-13 Top 14 season. For 2013-14, the cap was increased to 10 million, and in addition youth players are excluded from the cap unless their salaries are more than 50,000. The 10 million total cap remained in place for three seasons (through 2015-16); the agreement allowed for the threshold for exclusion of youth players to be adjusted before any of those seasons, but no such adjustment was made. The 10 million cap was later extended through the 2018-19 season. Additionally, each club that has a member of the France national rugby union team on its roster (more specifically, one of the 30 players named by the French Rugby Federation to the so-called "elite squad") is allowed to exceed the cap by a set amount per national team member. This amount was fixed at 100,000 through the 2015-16 season, and increased to 200,000 starting in 2016-17.
