Also, have a look at the 'discount method' they're using, it's well-covered in the 'independent-experts report' (IE) but they use a 14%-16% discount rate, which is actually quite high, compared to many of the ASX 'biotech/pharma' rated and/or valued by Morningstar (CMC seems to back their platform with Morningstar data, and additionally another's, more selectively), which generally sit around thee 6.5-8.5% mark...
So the 'discount rate' appears to be nearly double what I've seen traditionally over several years...
