    Abstract:
    Marginally stable perfect fluid tori with uniform distribution of
    specific angular momentum are determined in the Reissner-
    Nordström-(anti-)de Sitter black-hole and nakedsingularity spacetimes.
    Toroidal configurations are allowed only in the spacetimes admitting
    existence of stable circular geodesics. The configurations with
    equipotential surfaces crossing itself in a cusp allow accretion (inner
    cusp) and/or excretion (outer cusp) of matter from the toroidal
    configuration.
