The same-size median among plans reporting any Schedule C compensation was $82.08 per participant. Administrative expenses on Schedule H were $927,760. Investment costs deducted inside mutual funds and other pooled vehicles are not itemised on Form 5500, so these figures are a floor rather than a full cost.
