but the $56 million for macquarie is not for their shares, but instead for the management rights. Which is an entirely separate asset.

Even if this were not the case it is no longer against the law to offer a "special benefit" to an individual shareholder. It used to be out and out banned, but this was changed with the CLERP reforms such that now special benefits just have to be fully disclosed. Or at least that is my recollection.
