NHL Buyout Rules Explained
By Mark Powell

Another NHL contract buyout window has passed, and while it's a particularly dry period of the offseason, many fans are wondering exactly how these complicated scenarios play out, and what the ramifications may be. So allow us to provide a brief explainer.
NHL Buyout Window
The NHL's second buyout window began on Monday, July 29 and ended Wednesday, July 31 for teams that have player who are arbitration-eligible. The first buyout period ran from the conclusion of the Stanley Cup Final to June 30.
With Shattenkirk joining the UFA group after his buyout, he had the 7th most points out of remaining UFA's, tied with Pat Maroon (28 Points). https://t.co/JXIMIMxzPx]

NHL Buyout Rules Explained
Any player's contract may be bought out, although the remaining money and years left on the contract makes doing so not feasible for certain players (hint: Jack Johnson of the Pittsburgh Penguins).
However, the NHL's buyout rules are unique, as they have a specific age measurement of 26 as to when players will receive more or less money when teams want their contracts off the books. For example, if a player in under the age of 26, a team can buy out their contract for 1/3 of the remaining value on the deal. If a player in over 26, they are responsible for 2/3 of the remaining value. This puts more onus on teams honoring the contracts of veterans, as younger players likely have more value on the open market.
The NHL buyout window is officially open! Teams have until 5pm EST on June 30th to buyout players to free up a roster spot and/or save money on the 2019-20 salary cap. For rules on how the buyouts work check out this handy reference from Cap Friendly: https://t.co/hqw8MRVU3K

When can an NHL player be bought out?
Any player, regardless of status or contract, can be bought out. However, before doing so, they must be placed on waivers. Should that player clear waivers, they can then be bought out in full and thrown in the free agency pool.
