I'm not following what exemption from the Form M-1 filing requirement you're relying on here.
Brian, EBECatty is referring to the 2020 M-1 instructions, page 2, lower right-hand column:
Re the basic question, I have not discussed the < 80% ownership question with a state insurance department, but I have sought informal advice from the Texas Dept. of Insurance regarding the Affiliate Service Group MEWA (e.g., with incorporated partners in a law firm) as well as the "transition services agreement" issue following an M&A transaction (which is another M-1 filing exception for the 410(b)(6)(C) period) and was told that TDI was aware that in these situations a MEWA existed, but it was not an enforcement priority for them.
