"As outlined in our recent letter to the Yahoo board, unless we made progress with Yahoo towards an agreement by this weekend, we will reconsider our alternatives, and provide updates as appropriate next week," said Liddell. "We have yet to see tangible evidence that our bid substantially undervalues [Yahoo]; in fact, we see the opposite."
