N2 - Let T be a complete local (Noetherian) ring containing the rationals, and let C be a finite set of incomparable non-maximal prime ideals of T partitioned into m subsets C1,... , Cm. We find necessary and sufficient conditions for T to be the completion of an excellent reduced local ring A with precisely m minimal prime ideals J1,.. . , Jm such that, for each i = 1, 2,... , m, the maximal elements of the set {Q ε SpecT | Q ∩ A = Ji} are precisely the elements of Ci. We also find necessary and sufficient conditions for T to be the completion of such a ring A for the case where A need not be excellent.
