A great explanation re: the new CBA and how the amount of rebates have changed: especially as it relates to the Yankees
Here is the pertinent part from the article re: CBA:
"The Yankees expected to receive money not just from a decreased luxury tax rate
but a complicated clause in the collective-bargaining agreement called the
MLB's revenue-sharing program works like this: The league taxes every team at
34 percent on its local revenue, pools the money and distributes it evenly.
Beyond that, as a means to funnel more money to lower-revenue and smaller-market
teams, it uses a variable tax rate that forces teams with big revenue streams in
big markets to pay more on top of the 34 percent.
The flaw in the system is that some teams in the top half of market size are
not in the top half of revenue, meaning big-market teams are getting
revenue-sharing dollars like small markets. In recent years, these teams have
included Washington, Atlanta and Toronto. Starting this season, such teams were
mandated to give a portion of that money back to the bigger-market teams – 25
percent in 2013, 50 percent in 2014, 75 percent in 2015 and 100 percent in 2016.
The catch: Teams needed to be under the luxury tax threshold to qualify.
Considering the money would be distributed proportionally to contributions,
the Yankees expected their rebate to be significant – upward of $45 million
between 2014-16 if they kept their payroll below $189 million for those seasons,
according to two sources."
The article goes on to explain that Washington and probably Atlanta, Toronto will end up not being payors into the rebate lowering the pool.
