From what I understand - RMS is a company that IP invented to handle their property, reduce their liability and reduce their tax burden. I have made signs for their offices and they always want them as small as possible and done in colors that will not show up. They like to stay hid!
You may be thinking about the entities John Hancock set up to own the old KC land it bought from US Alliance, RMS is a independent company that owns/ manages lots of land for different investors.
