"The 2013 collective bargaining agreement eliminated re-entry waivers. If a National Hockey League player is being sent to an NHL affiliate team (AHL) and is put through waivers and cleared successfully, then his salary won't count against the respective NHL team’s salary cap (but he would still get paid his full salary, he would be making X amount to play in the AHL). There is an exception to this rule; if the player has a contract that took effect after a player's 35th birthday, then that player's salary would still count against the NHL cap.
If a player is claimed on waivers, then the claiming team is responsible for the rest of their contract. However if a player clears waivers and is sent down to the minors, but then recalled, and his salary is more than $105,000 in the AHL (essentially, any player who is not on an entry-level or two-way contract), he is subject to re-entry waivers where if a team claims him they are only responsible for half the salary for the remainder of the contract."
I was under the impression that this was kept intact with the exception that only one thing was eliminated fro the 2005 CBA as far as waivers.
