The Average Base Salary for Senior Roster Non-Designated Players is calculated by sorting the Roster Category to include only players in the Senior Roster Category (No DP, No Supplemental, No Supplemental Reserve) and calculating the Average of the base salaries of Senior Roster Category players.
The Average Base Salary by Roster Spot is calculated using the senior roster for each team by (1) sorting players per roster from highest to lowest based on their base salary (2) Taking the 18 highest paid players on the roster (including DPs) and assigning them to spots 1-18 in order of their base salary (highest to lowest) (3) Averaging the salaries by roster spot for each spot (e.g. avg. of 24 Roster Spot #1s, avg. of 24 Roster Spot #2s, etc.).
The league allows each club to acquire up to three players whose total compensation and acquisition costs exceed the maximum budget charge. Clubs are responsible for any amount exceeding the respective DP's budget charge. The rule was first introduced in 2007 in order to give clubs more flexibility to sign lucrative deals with marquee players.
Players on the Supplemental and Reserve Roster are "off budget." There are two kinds of Supplemental Roster players: Those occupying roster spots 21-24 who must earn at least the Senior Minimum, and those occupying roster spots 25-30 who may earn the Reserve Minimum, but must be 25 years old or younger. Spots 29 and 30 are limited to Homegrown players.
