Thanks for the analysis, Fasctrack. A couple of other things to consider....
1)Cal's estate is owed some $800K in back pay and loans. I would expect to see this paid off relatively soon, perhaps over the course of the next year or so. This would certainly mitigate the estate's need for any other short-term cash from sales of stock
2)FASC is definitely Cal's legacy; the estate and its heirs obviously have knowledge of this, and to this end, there may be some special provisions in the estate with regard to the handling of these shares.
