Contract terminations
A team and player may mutually agree to terminate a player's contract at any time. All players must clear waivers before having a contract terminated.

Buyouts can only occur at specific times of the year. For more details on contract terminations as buyouts:

Teams may buy out player contracts (after the conclusion of a season) for a portion of the remaining value of the contract, paid over a period of twice the remaining length of the contract. This reduced number and extended period is applied to the cap hit as well.
 * If the player was under the age of 26 at the time of the buyout the player's pay and cap hit will reduced by a factor of 2/3 over the extended period.
 * If the player was 26 or older at the time of the buyout the player's pay and cap hit will reduced by a factor of 1/3 over the extended period.
 * If the player was 35 or older at the time of signing the contract the player's pay will be reduced by a factor of 1/3, but the cap hit will not be reduced over the extended period.

Injured players cannot be bought out.

Imports
This section is for players who were not previously on contract with NHL teams in the past season. Listed is their previous team and the league that they belonged to.

Trades
* Retained Salary Transaction: Each team is allowed up to three contracts on their payroll where they have retained salary in a trade (i.e. the player no longer plays with Team A due to a trade to Team B, but Team A still retains some salary). Only up to 50% of a player's contract can be kept, and only up to 15% of a team's salary cap can be taken up by retained salary. A contract can only be involved in one of these trades twice.

Hover over retained salary or conditional transactions for more information.

Waivers
Once an NHL player has played in a certain number of games or a set number of seasons has passed since the signing of his first NHL contract (see here), that player must be offered to all of the other NHL teams before he can be assigned to a minor league affiliate.
