down and then is called up again, he does not have to clear waivers to be sent down again unless he has played ten games or has been "up" for 30 days. Re-entry waivers The 2005 NHL-NHLPA collective bargaining agreement (CBA) introduced "re-entry waivers." With limited exceptions, any player who was subject to waivers before assignment to the minors must clear re-entry waivers before being called back up if said player is on a one-way contract or a two-way contract with an AHL salary in excess of $105,000. Exceptions are players who have played in over 320 professional games (180 for goaltenders) and have not spent more than 80 games on an NHL roster in the past two seasons or 40 games during the previous season. The procedure to make a claim on re-entry waivers is the same; however, teams who claim players on re-entry waivers are only responsible for half the salary and cap hit, while the original team is responsible for the other half, unless the claimed player is later assigned to the AHL again before his contract has expired, in which case the salary and cap hit comes off the books of both teams. The CBA ratified in January 2013 eliminated re-entry waivers. Return waivers Players who play ice hockey outside North America during a regular season and who are not on loan from or whose playing rights are not already owned by an NHL club (that is, the player is not already on a team's 90-player reserve list such as a qualified restricted free agent or a draft pick) must also be placed on waivers if they are signed to play in the NHL. If the player is picked up by another NHL club on waivers, the player must be placed on waivers again before a further trade or loan can take place. Unconditional waivers A third type of waivers, "unconditional waivers," applies when a player is to be given an unconditional release from his contract, either by buyout or for the purpose of contract termination. A team may terminate the contract of a player for breach of contract at any time. Additionally, a player and team may mutually agree to terminate a contract at any time. This process can only be completed if the player clears unconditional waivers. In order to buy-out a player, NHL teams give notice to the player and the league that
