Corrections to factorization approximations for the matrix elements of B<SMALL></SMALL>0 - <span style="text-decoration:overline">B</span><SMALL></SMALL>0 meson mixing are computed within QCD sum rules approach. Both nonperturbative and perturbative corrections are analyzed. Nonperturbative corrections are well under control and small while perturbative corrections are found to be of order 10%.
