Abstract It is shown that the phase factor associated with the "orthogonality phase shift" from a bound state should be factored out of the S matrix. A crucial test of this statement is found in a study of the final state interaction of an inelastic process which ends in a channel involving the bound state. If it is assumed that the sum of the Born series for the S matrix gives a right answer after the effect of the bound state is separated in terms of the orthogonality phase shift, an agreement with Watson's result obtains only when the S matrix has the factored structure.
