Welfare Benefit Plan - Combined Form 5500

[Guest JimD-EBR]

If an employer has various large welfare plans (i.e. health, dental, vision, term life, disability, etc.) is there any guidance on whether or not single 5500s need to be filed for the various coverages or if a combined 5500 can be filed for all? Each coverage is provided through a different carrier, so there are multiple schedule A's. If the health plan is self-funded (with stop-loss) does that make a difference in the method used? If optional where could one find the advantages/disadvantages of one method over the other?
