## Abstract Let __R__ be a Gorenstein ring of finite Krull dimension and __t__ β __R__ a regular element. We show that if the quotient map __R__ β __R/Rt__ has a flat splitting then the transfer morphism of coherent Witt groups Tr~(__R/Rt__)/__R__~ : $ \widetilde W^{i} $(__R/Rt__) β $ \widetilde W^
