"Not all welfare plans are required to annually report on Form 5500 or Schedule C. A plan that covers less than 100 participants at the beginning of the plan year -- and which is unfunded, fully insured, or a combination of both -- is exempt from the annual reporting requirement. See [DOL] Regulation section 2520.104-20 and 2009 Instructions to Form 5500, page 4. Where such a welfare plan has 100 or more participants at the beginning of the plan year, it is subject to the annual reporting requirement but is not required to file Schedule C."  MORE >>
