Debenture holder is just a creditorI think the question should be, how do you become a debenture holder of the Holman-Barnes Group? The supporters should pool their money.
However reading the last yearly report they have a debenture loan of $2000 and appears all the board are debenture holders, which is rather peculiar but maybe its a tax thing.
As its a private company actually have no idea who owns HolmanBarnes group. Could be one person!
