Normally, the company creates a number of new shares when the company goes public, offers the new shares to the public and uses the income to... well, to do something. Existing shareholders typically promise not to sell their shares for six months or so. But it's perfectly possible to have some existing shareholders offer a few shares for sale instead of emitting new shares. Unconventional, and I'm sure some people disapprove of it for that reason, but perhaps the company doesn't need the cash and the existing shareholders don't want the dilution?
