Why are not all Lost actors renewing their contracts?

Potential Spoiler

Reuters writes:

Lost producer Touchstone Television has offered all original members of the large ensemble cast a substantial salary bump in exchange for an additional year to the actors’ current contracts. The studio’s pre-emptive offer would see the actors earn almost $80,000 each an episode next season, the show’s third, up from a range of about $20,000-$40,000 for most cast members this season.

All original cast members, including Matthew Fox, Evangeline Lilly, Josh Holloway, Naveen Andrews, Dominic Monaghan, Terry O’Quinn, Jorge Garcia, Daniel Dae Kim, Yunjin Kim and Harold Perrineau, have been offered the same deal and are expected to take it. Fox, who plays the pivotal role of Jack, is said to have earned an extra bonus of at least $250,000.

The really interesting part of the Reuters article is not the raises, but the fact that
The Hills Have Eyes star Emelie de Ravin who portrays Lost’s Claire is not mentioned among the original cast members who have been offered extended contracts.

Is this a miss by Reuters or have we seen the last of Claire?
As always, with Lost, you never know which character might get killed or get kidnapped by the Others but I hope Claire will stick around a while longer.
