In this paper we first tackle certain basic questions concerning
the Invariant Basis Number (IBN) property and the universal stably
finite factor ring of a direct product of a family of rings. We
then consider formal triangular matrix rings and obtain
information concerning IBN, rank condition, stable finiteness and
strong rank condition of such rings. Finally it is shown that
being stably finite is a Morita invariant property.
