Mr. Keis laid it out very plainly, nothing here; only problem is when Halliburton notified the SEC of their change in procedures; 10 out of 15 companies do it.
And don't forget, Larry's "clients" bought their stock THIS YEAR.........duh.
That's really the kicker isn't it. Buy your stock 2 to 2 1/2 years after the change was reported and then sue over it.
