By PEB's own commentary, they have converted 2 of the 4 'transformative' companies with KP and CMS to go.
Why are KP and CMS so very very very important?
PEB has been selling hype and hope to fund its largely unsuccessful commercialization startegy in the US - dare I say very successfully - but the evidence to date is that it was all a pack of hype and truth be known, accounting trickery.
