Nontopological solitons can be formed during a phase transition in the early Universe as long as some net charge can be trapped in regions of a false vacuum. It has been previously suggested that a particle-antiparticle asymmetry would provide a source for such trapped charge. We point out that, for the model and parameters considered, statistical fluctuations provide a much larger concentration of charge and are, therefore, the dominant source of charge fluctuations in solitogenesis.
