  We derive the Smarr formula for a five-dimensional spacetime which has a
magnetic "bolt" in its center and is asymptotically R^(3,1) x S^1.
Supersymmetry - and so the BPS-bound - is broken by the holonomy. We show how
each topological feature of a space-like hypersurface enters the mass formula
and which ones in particular give rise to the violation of the BPS-bound.
