It is proven that the Trotter product formula converges in the norm of a symmetrically normed ideal of compact operators away from t 0 >0 if the Kac operator (the transfer matrix) F(t)=e &tBΓ2 e &tA e &tBΓ2 belongs to this ideal for t=t 0 . The result is generalized to the Trotter Kato product formu
