As I noted in a prior post, the proper procedure when a company gives out material information selectively is to follow-up with an 8-K filing that describes the selectively-disclosed information. Doing this promptly absolves the company from legal liability under Reg FD.

None or very very few are about disclosure to anyone and everyone who called even if it was material and they didn't file an 8-K
