It is what is known as a contributing share ( hence brbCa....C for contributing). In this case you need to contribute another 19 cents to the company at a later time to convert it to a fully paid ordinary share. So if you buy on market for 44c then later convert it by paying the 19c it men's you have bought an ordinary share for a total of 63c . Bingo, as simple as that. The difficult part is to get hold of them as not many on issue and tightly held.
