Read this first: Schedule H shows the audit fee only when the plan pays the auditor. Plans whose sponsor pays the audit fee directly are not included, and for single-employer 401(k) plans that is most of them (only 8% of audited 401(k) plans with 200-499 participants report a fee). The figures describe the plans that report a fee; treat them as a market reference, not as a quote.
