UAL Buyout Plan Put to Vote: Shareholders in UAL Corp. were to vote today in Chicago on a $4.9-billion employee buyout plan, and one institutional shareholder said it favors the transaction. The California Public Employees Retirement System, which holds 198,200 shares, or 0.8% of UAL, said it will vote for the buyout. Many industry analysts and investors believe shareholders in the holding company for United Airlines will endorse the plan, under which about 60,000 employees would receive at least 55% stake of the company in exchange for six years of wage and work-rule concessions. Employees and UAL management on Dec. 15 first announced an agreement in principle on the sale.
