What do you need to disclose regarding brokerage commissions/investment fees in Part I of Schedule C? Specifically what are they referring to when they say: "include brokerage fees and commissions only if the broker is granted some discretion"? The cite they give on the form seems to refer to brokers executing securities transactions. in our case we are a TPA and we are concerned about subsidies received from mutual fund companies. The 5500 seems to be only concerned with fees paid by the plan. money received from other sources dont seem to be the issue to me. sometimes we are a fiduciary and we disclose and offset under frost but this does not seemt to be relevant in this question.
