The voting shares of McCormick MKC-V are held primarily by employees, retirees and others who are closely associated with the Company. A buyout will not happen unless this group thinks it's a really good deal... http://finance.yahoo.com/q?s=mkc-v&ql=1
Who do you think would be interested in proposing a buyout offer? I think food companies would be reluctant because MKC most likely sells to a majority of major food companies. This is why Coke or Pepsi are not in the restaurant business....
Have heard discussion of foreign based food companies that want to buy U.S. companies with brand name recognition, It is a way to enter the U.S. market without starting from scratch. For example, there is talk of a Brazilian company making a run at Sara Lee (or maybe this has already happened?).
You can buy the voting shares, but they don't trade much, definitely a very long term buy and hold stock. Can't trade them, just invest. The spread is usually around 50 cents and only a couple hundred trade per day.
