An SC 13G filing on jan 24, 2012 was filed by SRB Corp. which is owned by Plymouth Rock Company. There is no way Plymouth Rock could buy out Safety and Plymouth Rock either holds the investment because they think it is a good stock or they might believe Safety is a takeover candidate. At this point, Plymouth Rock owns 8.8% of Safety. I doubt that Safety really loves the idea of a competitor owning 8.8% of its stock. It's always possible that Plymouth Rock could be acquiring the stock for an investment group.
