Note that they are supplementing the original notice to GTE(" . . . the American Stock Exchange [Amex] provided the Company with a letter dated August 17, 2006 that supplements and updates the Exchange's original July 18, 2006 notice.").
Lawyers often supplement when they are trying to enhance, i.e. when they are worried about the original charges. And, it took the AMEX a month to supplement the original notice. A good lawyer does not need a month to supplement and enhance strong charges. They would have been clearly presented with specificity from the beginning.
