The sales were part of "automatic" sales program. I'm not real sure how the rules work, but assume the sales were set up before the extention of the refined coal credit. It appears the sales have stopped (agreements to sell must have expired).
Most insiders have only a window to buy or sell. As we get closer to earnings there cannot be any trades by company officers.
Does that apply to the automatic sales? The SEC forms indicated the sales were "automatic". On earnings, I assume Q4 will be break even with the Calogon settlement.
