The derivation of absolute (moduli-independent) U-invariants for all N > 2 extended supergravities at D = 4 in terms of (moduli-dependent) central and matter charges is reported. These invariants give a general denition of the \topological" Bekenstein{Hawking entropy formula for extremal black-holes
