Cooley and Biglari resigned from CCA board effective last week.
I don't read much into this, it is such a small position for BH.
Since CCA recently hired a new CEO and changed the way they are structured, I would guess Phil and Sardar are moving on. My recollection is there are some very expensive change of control rules until 2016 to prevent any buyout of the company, but I could be mistaken on this.
