The rules are quite complicated. It involves the total minutes played during the Regular Season of domestic players for one team, as the team which has the highest minutes played by domestic players at the end gets extra payment by the federation.
The rules are:
Option 1: 5 import (open passports) + 5 domestic players (this team will be included in the award of the playing minutes for domestic players)
Option 2: 6 import players (open passports) - 6 domestic players (choosing this option the team has to pay a luxury tax and will not be included in the award for the domestic players)


Ratio Imports/Bosman can change from game to game. So the team could have signed even 3 imports and 4 Bosmans based on the condition that for the game they have to meet league limits (above).

The deadline to sign domestic players is end of February. Non-Italian players can sign until the beginning of the play-offs.

The league allowed the signature of a maximum of 18 contracts throughout the season.
