They use a different cap calculation to determine the maximum salaries, which is based on 42.14% of projected BRI rather than 44.74%. In 2005 the sides negotiated a different formula for setting the salary cap but not maximum salaries, so the two became decoupled, and this continued in the 2011 agreement. For this reason the maximum salaries are not actually 25%, 30% or 35% of the cap, and instead are a slightly lower amount. For example, even though the salary cap for 2011-12 is $58.044 million and 25% of this amount is $14.511 million, the 0-6 year maximum salary is actually $12,922,194. In addition, for 2012-13 a 5.8% increase in maximum salaries was agreed to, even though the salary cap stayed the same as 2011-12.
