Schedule A for Welfare Benefit Plan?

I have it in my mind that a Schedule A is not required to be attached to a 5500 for a service provider of a welfare benefit plan where the service provider did not pay any fees or commissions to an insurance agent.  Am I thinking correctly?  Thank you.

I do not believe the issue of commissions is relevant.  I reviewed the instructions on the IRS website, indicates the requirement is a plan provided through insurance contract, Blues, etc.

Even though no commissions were paid, there were probably premiums paid that should be reported on page 4

Page 21 of the Form 5500 Instructions - "Schedule A (Form 5500) must be attached to the Form 5500 filed for every defined benefit pension plan, defined contribution pension plan, and welfare benefit plan required to file a Form 5500 if any benefits under the plan are provided by an insurance company, insurance service, or other similar organization (such as Blue Cross, Blue Shield, or a health maintenance organization)."
