Lehman Brothers, currently the fourth largest securities firm, may be a target for a hostile takeover bid. Lehman's current management is unwilling to negotiate with buyers at the company's current stock level. Buyers from Korea and China have already walked away from previous negotiations as the investment bank continues to demand too high of a price. Shares of Lehman Brothers have already fallen 77 percent over the last year as the company has struggled with high credit losses of nearly $8.2 billion over the last 12 months.
