A look at some of the key details from the tentative collective bargaining agreement announced by the NHL and the players' association on Sunday morning:

— Players will receive $300 million in transition payments over three years to account for existing contracts, pushing their revenue share over 50 percent at the start of the deal.

— Players gained a defined benefit pension plan for the first time.

— The salary cap for this season will be $70.2 million before prorating to adjust for the shortened season, and the cap will drop to $64.3 million in 2013-14 — the same amount as 2011-12. There will be a salary floor of $44 million in those years.

— Free agents will be limited to contracts of seven years (eight for those re-signed with their former club).

— Salaries within a contract may not vary by more than 35 percent year to year, and the lowest year must be at least 50 percent of the highest year.

— There were no changes to eligibility for free agency and salary arbitration.

— The threshold for teams to release players in salary arbitration will increase from $1.75 million to $3 million.
