Hi D,
PBIOA's are a bargain option in my view. 2012 expiry and .20 to take them up ..... at current levels there is very little premium for the best part of five years of upside ... amazed these are not trading as high as .18.
Very tightly held though, only 7million on issue, and hot copperites with a pbi bent are holding at least 20% of those i reckon.
