Mass, angular momentum and charge are all a part of the Kerr-Newmann metric tensor.

S. Hawking gives me the impression that he has enough distaste for time travel paradox's that his stand on more than one point in relativity is influenced more by that than by what is already known. I don't immediately discount possibilities based on a pseudo-paradox. As far as I'm concerned, remote observers can observe information (and macroscopic objects for that matter) cross the event horizon, but only while it is changing in size. The geometrodynamics of this process will prevent any grandfather paradox. However if the hole has more angular momentum or charge in comparison to mass in the same units than is currently thought possible then there are no real event horizon coordinates, but closed time-like loops would form re-introducing the paradox. Even so I don't discount the possibility of those kinds of holes either.
