The WNBA and the WNBA players association have reached a new eight-year collective bargaining agreement, the two sides announced Friday.

The new deal includes a "Time off Bonus" of up to $50,000 players can earn for limiting their playing time overseas to three months or less in the off season. Some WNBA players spend up to six months playing overseas.

"We really wanted to offer an incentive for players to stay state side or limit their play overseas," WNBA president Laurel Richie said during a conference call with reporters.

The two sides also agreed to add a 12th roster spot, salary cap increases and reduced revenue sharing thresholds, allowing players to potentially share in league revenue growth.

The league trimmed team rosters from 13 to 11 prior to the 2009 season.

The agreement also reduces the number of times a team can subject a player to "core" status from five to four.

A franchise can designate one player as a core player and receive exclusive negotiating rights in exchange for an offer of a one-year, fully-guaranteed max salary deal.

Both sides can opt out of the agreement after the sixth season.
