If you mean material event as in the SEC requiring an 8-K, I don't recall in the DM days when we got our 1st RB settlement it was 8-K'd, but it was in a PR.
The 1st one was with wolverine data I think, and it was about 38K per year, which is not that "material" either.
NDA's can stipulate no comment at all, I'd think?
