Serious question (sorry)
Why does there need to be announcements of takeovers?
HP is traded on the market, Xerox can buy all the HP shares it wants at the 'true' price - but for rules stopping it.
The rules are in place to stop shady consortiums of buyers picking up a company without anyone knowing about it, but it's not clear who this rule benefits (except protecting large corporations)
The only legitimate objection would be monopolies concerns, but the 15% rule applies even when there is no competition question
