I would say there was plenty of value if all they had to sell was the ability to use the name. And they can still sell the product so they are not loosing sales with the sale of the name. It's simply that Stanley now gets to make some profit on the sales of Craftsman tools.
This will be interesting to see. Stanly still has to manufacture or pay some one to manufacture the tools, and they are out 900 mil. On top of that Sears is probably the largest retailer of Craftsman tools, if they go out of business there is a lot of slack that will need to be taken up.
