unfortunately incorrect... K's do not have a conversion clause
however the P's do; and why it can be converted. that is the very reason why some should be buying up the K's regardless because it is not the same, though the class may be.
H's will end up paying for some of the expenses, and they will... that makes K's even better a bargain than H's....
Right now P's are the best, then K's imo, then H's and commons.
