Will it Take Two to Tango Past Barnes & Noble's Poison Pill?

Late last year, when billionaire Ron Burkle's investment firm, The Yucaipa Companies, bought up millions of shares in book retailer Barnes & Noble (BKS), making him the second-largest stakeholder in the company, its board responded by implementing a "poison pill" measure designed to stop a single stockholder from setting up what would effectively be a hostile takeover. Yucaipa was stopped in its buying tracks with 17.8% of Barnes & Noble's shares.
