The proof of Lemma 3.4 in $\left[ \text{F} \right]$ relies on the incorrect equality
${{\mu }_{j}}(AB)={{\mu }_{j}}(BA)$
for singular values (for a counterexample, see [S, p. 4]). Thus, Theorem 3.1 as stated has not been proven. However, with minor changes, we can obtain a bound for the counting function in terms of the growth of the Fourier transform of
$\left| V \right|$.
