Sorry, let me rephrase: If I own 100% of a company worth 100$, sell off 30% of it through an IPO, I make 30-100-pick a number$ and I still own 70%... etc.
There just doesn't seem to be an advantage to merging into TGLO other than time constraints or maybe they think that they can get a higher price per share through a merger and by getting directly on the secondary markets instead of passing through underwriters? (It's a very, very long shot but maybe.)
